While living in a land completely unlike the world she grew up in beyond The Wall, she is caring for her child and learning to read and write.
In the process of that learning, she stumbled upon arguably the most game-changing news in the history of the series: the annulment of Rhaegar’s marriage to Elia and subsequent marriage to Lyanna Stark.
Gilly may not be everybody’s favorite character, but it’s hard to deny that her lot in life has vastly improved since escaping Craster, and she has risen to the occasion.
