A Clash of Kings Edit
Gilly hopes to get Jon Snow to help her escape. She is pregnant and fears, if it is a male child, Craster will sacrifice it. Craster had a tendency to sacrifice his male children to the Others, however he hasn't had a male child in a while. He has sacrificed all his sheep, and Gilly thinks that he will start sacrificing the dogs too soon.
She catches Ghost breaking into the hutch where she is trying to breed rabbits. She yells at him attracting Jon's attention. Jon tells her that the Watch will compensate her for the rabbits. She is terrified of the direwolf, and Jon believes that its because she was worried that it would tear her child out from her belly.
Later she comes to him again. Sam gives her his cloak so no one will know that he is talking to one of Craster's wives (they were warned not to). She tells him that Mormont gave Craster a crossbow for the rabbits, but that's not what she wants. As Robb is king in the north and a king protects people, she hopes Jon will help her. However Jon refuses, but Sam tells her that if they come back the same way that he will help.
A Storm of Swords Edit
After being attacked on the Fist of the First Men by Wights, the Night's Watch escape for Craster's Keep. Gilly gives birth to a son. However Craster is killed before he sacrifices the child, and in the confusion Gilly flees south with Samwell.
On their way to The Wall, Samwell Tarly and Gilly spend the night at Whitetree, where they get attacked by a dozen wights, including Small Paul and Chett. They escape with the help of a man dressed all in blacks and greys astride a great elk, who appeared with thousands of ravens.
A Feast for CrowsEdit
Gilly talks with Jon after he is elected Lord Commander. Val sends her frequently to plead for the release of Mance Rayder. Jon sends Gilly and her son to accompany Samwell Tarly and Maester Aemon Targaryen to Eastwatch-by-the-Sea. He swaps Gilly's son around with Dalla's son, causing Gilly to weep.
