who is the person who saved jon snow
Jon Snow (character) In "The Red Woman", Davos Seaworth, Dolorous Edd, and other brothers of the Watch loyal to Jon barricade themselves in a room with Ghost and Jon's body, and an attack by Thorne and his men is thwarted by the arrival of Tormund and his wildlings. Davos encourages Melisandre to attempt to resurrect Jon in "Home", and though the ritual at first seems to fail, Jon suddenly awakens. After hanging Thorne, Olly, Bowen Marsh, and Othell Yarwyck for their treason in "Oathbreaker", Jon gives command of the Watch to Edd and prepares to leave Castle Black. In "Book of the Stranger", he is reunited with his half-sister Sansa Stark, who has fled her abusive husband Ramsay Bolton and now seeks Jon's aid in crushing the Boltons. Jon is hesitant until a threatening message arrives from Ramsay demanding Sansa's return, and announcing Ramsay's possession of their brother Rickon. Jon, Sansa, Davos, Tormund, and Brienne of Tarth set off to recruit an army to take back Winterfell and rescue Rickon from Ramsay in "The Broken Man", but their forces grow to only half the size of Bolton's. As the armies face each other in "Battle of the Bastards", Ramsay murders Rickon to enrage Jon, who rushes in with murderous fury. A devastating battle ensues in which the outnumbered Stark forces are nearly slaughtered, until the Knights of the Vale from House Arryn arrive with Sansa and Petyr Baelish, and attack the Bolton army from the rear. Jon chases Ramsay back into Winterfell and beats him savagely, stopping before killing him. Sansa subsequently feeds Ramsay to his own hounds. In the season finale episode "The Winds of Winter", Bran Stark has a vision of the past which shows Ned reuniting with a dying Lyanna in the Tower of Joy. She makes him swear to protect her sonâ€”Jon.[36][37][38] Meanwhile, the Northern lords name Jon the King in the North.
Samwell Tarly Jon sends Sam to Oldtown to become a Maester, accompanied by another brother, Dareon (who is appointed as a recruiter), Maester Aemon (who Jon fears will be sacrificed by Melisandre for his royal blood) and Gilly and her baby. During the voyage to Braavos, Gilly grows despondent, and Sam realises that Jon had swapped Gilly's baby with Mance Rayder's newborn son lest he be sacrificed as well. Aemon falls ill during the voyage and they are forced to spend their money on a healer and lodging in Braavos. In Braavos, Sam also encounters Arya Stark, though he does not realise her identity. Aemon hears of his great-grandniece Daenerys Targaryen and her dragons, and comes to believe that she fulfills the prophecy of a "prince that was promised", asking them to inform the Citadel. Dareon decides to desert and Sam fights him, before being thrown into a canal. He is rescued by a Summer Islander, Xhondo, who offers Sam and Gilly passage to Oldtown. Aemon ultimately passes away early in the journey, and Sam and Gilly briefly become lovers in their grief.
