The ritual seemingly fails but Jon suddenly awakens. After hanging Thorne and the other ringleaders of Jon's assassination, Jon passes his command to Edd and declares he has been released from his Night's Watch vows by death.
He makes plans to leave Castle Black. Jon is reunited with his half-sister Sansa Stark , who has fled her abusive husband Ramsay Bolton and seeks Jon's aid in retaking Winterfell from the Boltons.
Jon refuses until a threatening message arrives from Ramsay demanding Sansa's return and announcing Ramsay's possession of their brother Rickon.
Jon, Sansa, Davos, and Tormund travel the North to recruit an army to take back Winterfell and rescue Rickon, but many houses refuse to support them and their forces grow to only half the size of Bolton's.
Jon plans for battle. As the armies assemble, Ramsay kills Rickon in order to provoke Jon and lure the Stark forces out of position. The ploy works and the outnumbered Stark forces are surrounded and nearly slaughtered, but then the Knights of the Vale of House Arryn arrive with Sansa and Petyr Baelish and rout the Bolton army.
Jon pursues Ramsay back into Winterfell and subdues him, but allows Sansa to decide his death. Jon gathers the lords of the North and warns them of the threat of the White Walkers.
The Northern lords declare Jon the new King in the North. Meanwhile, Bran Stark has a vision of the past which shows Ned reuniting with his dying sister Lyanna in the Tower of Joy.
She makes him swear to protect her son with Rhaegar Targaryen , who is revealed to be Jon. Jon prepares the North's defense against the White Walkers.
He receives a message from Cersei Lannister that he swear his allegiance to her, as well as an invitation to Dragonstone from Daenerys Targaryen 's Hand Tyrion.
In a message from Sam, Jon learns Dragonstone has a deposit of dragonglass, to which the White Walkers and wights are vulnerable.
He decides to meet with Daenerys. Daenerys wants Jon to bend the knee but Jon refuses, insisting that the White Walkers are a threat to all of humanity.
Tyrion persuades Daenerys to let Jon mine dragonglass as a gesture of goodwill. Jon discovers cave drawings of the First Men and the Children of the Forest fighting the White Walkers and invites Daenerys to view them.
As part of the plan to convince Cersei that the army of the dead is real, Jon leads an expedition beyond the Wall to capture a wight to provide proof of it.
During the mission, when Jon kills a White Walker, the wights it had reanimated are destroyed. He realizes that killing the Night King will kill the entire army of the dead.
When Jon and his party are surrounded by wights, Daenerys comes to their aid with her dragons. However, one of the dragons, Viserion, is killed by the White Walker's commander, the Night King, who prepares to kill another and Jon tells Daenerys and the others to escape.
Daenerys is forced to flee without Jon but Benjen arrives to rescue him, sacrificing himself. Later, Daenerys vows to fight the Night King with Jon and he swears fealty to her as his queen.

Having fallen in love,  Jon and Daenerys give in to their feelings for each other and have sex on their voyage north while unaware they are related by blood.
Jon returns to Winterfell and is reunited with Bran and Arya. He learns the Wall has been breached by the White Walkers. Though they have readied Winterfell for battle, Sansa and the Northern lords are angry over Jon bending the knee to Daenerys.
Jon's bond with Daenerys continues to grow, and he rides one of her dragons, Rhaegal. Sam tells Jon the truth about his identity as Aegon Targaryen.
Later, Jon reveals this to Daenerys. The White Walkers arrive and Jon attempts to engage the Night King in single combat but is stopped when the Night King reanimates the dead to fight Jon.
Jon attempts to pursue him to the Godswood, where Bran is waiting to lure the Night's King, but is cornered by the undead Viserion.
Jon prepares to fight Viserion, but the Night King is killed by Arya, destroying the army of the dead.
In the celebrations afterwards, Jon is praised by the wildlings. This troubles Daenerys, who fears the people of Westeros would prefer Jon as their ruler over her.
Jon is troubled by his blood relation to Daenerys, causing him to withdraw from their sexual intimacy. Jon assures Daenerys that he has no desire to take the Iron Throne, renouncing his claim for hers, but insists he must be honest with his sisters about his true parentage.
Jon tells Sansa and Arya, swearing them to secrecy, but Sansa sees him as a preferable alternative to Daenerys and tells Tyrion.
Jon leads the Northern forces to help Daenerys claim the Iron Throne. They take King's Landing and the city surrenders to Daenerys.
However, having been driven mad by her recent losses and betrayals, Daenerys burns the city, killing hundreds of thousands of innocent civilians.
Afterward, she declares she will wage war on the rest of the world. Arya and Tyrion warn Jon that Daenerys will view his heritage as a threat and she is a threat to the Starks.
Tyrion tells Jon that despite Jon's love for Daenerys, it is his duty to kill her to protect the people. Jon confronts Daenerys but, unable to dissuade her from further destruction, reluctantly kills her and she dies in his arms.

Eventually he adjusted to teetotalism and led a life characterized by abstinence, signing an abstinence pledge in The surgeons worked together conducting research on England's cholera epidemics, both continuing to do so for many years.
In , Snow began working at the Westminster Hospital. Snow was a founding member of the Epidemiological Society of London which was formed in May in response to the cholera outbreak of By , Snow and Greenhow's nephew, Dr.
Greenhow were some of a handful of esteemed medical men of the society who held discussions on this "dreadful scourge, the cholera ". In , Snow made an early and often overlooked  contribution to epidemiology in a pamphlet, On the adulteration of bread as a cause of rickets.
John Snow was one of the first physicians to study and calculate dosages for the use of ether and chloroform as surgical anaesthetics , allowing patients to undergo surgical and obstetric procedures without the distress and pain they would otherwise experience.
He designed the apparatus to safely administer ether to the patients and also designed a mask to administer chloroform.
Snow published an article on ether in entitled On the Inhalation of the Vapor of Ether. After finishing his medical studies in the University of London , he earned his MD in Snow set up his practice at 54 Frith Street in Soho as a surgeon and general practitioner.
John Snow contributed to a wide range of medical concerns including anaesthesiology. He was a member of the Westminster Medical Society , an organisation dedicated to clinical and scientific demonstrations.
Snow gained prestige and recognition all the while being able to experiment and pursue many of his scientific ideas. He was a speaker multiple times at the society's meetings and he also wrote and published articles.
He was especially interested in patients with respiratory diseases and tested his hypothesis through animal studies. In , he wrote, On Asphyxiation, and on the Resuscitation of Still-Born Children , which is an article that discusses his discoveries on the physiology of neonatal respiration, oxygen consumption and the effects of body temperature change.
At the same time, he worked on various papers that reported his clinical experience with anaesthesia, noting reactions, procedures and experiments.
Though he thoroughly worked with ether as an anaesthetic, he never attempted to patent it; instead he continued to work and publish written works on his observations and research.
Within two years after ether was introduced, Snow was the most accomplished anaesthetist in Britain. London's principal surgeons suddenly wanted his assistance.
John Snow studied chloroform as much as he studied ether, which was introduced in by James Young Simpson , a Scottish obstetrician.
He realised that chloroform was much more potent and required more attention and precision when administering it.
Snow first realised this with Hannah Greener, a year-old patient who died on 28 January after a surgical procedure that required the cutting of her toenail.
She was administered chloroform by covering her face with a cloth dipped in the substance.
However, she quickly lost pulse and died. After investigating her death and a couple of deaths that followed, he realized that chloroform had to be administered carefully and published his findings in a letter to The Lancet.
Snow's work and findings were related to both anaesthesia and the practice of childbirth. His experience with obstetric patients was extensive and used different substances including ether, amylene and chloroform to treat his patients.
However, chloroform was the easiest drug to administer. He treated 77 obstetric patients with chloroform. He would apply the chloroform at the second stage of labour and controlled the amount without completely putting the patients to sleep.
Once the patient was delivering the baby, they would only feel the first half of the contraction and be on the border of unconsciousness, but not fully there.
Regarding administration of the anaesthetic, Snow believed that it would be safer if another person that was not the surgeon applied it.
The use of chloroform as an anaesthetic for childbirth was seen as unethical by many physicians and even the Church of England. However, on 7 April , Queen Victoria asked John Snow to administer chloroform during the delivery of her eighth child.
He then repeated the procedure for the delivery of her daughter three years later. Medical and religious acceptance of obstetrical anaesthesia came after in the 19th century.
Snow was a skeptic of the then-dominant miasma theory that stated that diseases such as cholera and bubonic plague were caused by pollution or a noxious form of "bad air".
The germ theory of disease had not yet been developed, so Snow did not understand the mechanism by which the disease was transmitted. His observation of the evidence led him to discount the theory of foul air.
He first published his theory in an essay, On the Mode of Communication of Cholera ,  followed by a more detailed treatise in incorporating the results of his investigation of the role of the water supply in the Soho epidemic of By talking to local residents with the help of Reverend Henry Whitehead , he identified the source of the outbreak as the public water pump on Broad Street now Broadwick Street.
Although Snow's chemical and microscope examination of a water sample from the Broad Street pump did not conclusively prove its danger, his studies of the pattern of the disease were convincing enough to persuade the local council to disable the well pump by removing its handle force rod.
This action has been commonly credited as ending the outbreak, but Snow observed that the epidemic may have already been in rapid decline:.
There is no doubt that the mortality was much diminished, as I said before, by the flight of the population, which commenced soon after the outbreak; but the attacks had so far diminished before the use of the water was stopped, that it is impossible to decide whether the well still contained the cholera poison in an active state, or whether, from some cause, the water had become free from it.
Snow later used a dot map to illustrate the cluster of cholera cases around the pump. He also used statistics to illustrate the connection between the quality of the water source and cholera cases.
He showed that homes supplied by the Southwark and Vauxhall Waterworks Company , which was taking water from sewage-polluted sections of the Thames , had a cholera rate fourteen times that of those supplied by Lambeth Waterworks Company , which obtained water from the upriver, cleaner Seething Wells.
It is regarded as the founding event of the science of epidemiology. On proceeding to the spot, I found that nearly all the deaths had taken place within a short distance of the [Broad Street] pump.
There were only ten deaths in houses situated decidedly nearer to another street-pump. In five of these cases the families of the deceased persons informed me that they always sent to the pump in Broad Street, as they preferred the water to that of the pumps which were nearer.
In three other cases, the deceased were children who went to school near the pump in Broad Street With regard to the deaths occurring in the locality belonging to the pump, there were 61 instances in which I was informed that the deceased persons used to drink the pump water from Broad Street, either constantly or occasionally The result of the inquiry, then, is, that there has been no particular outbreak or prevalence of cholera in this part of London except among the persons who were in the habit of drinking the water of the above-mentioned pump well.
