Game Of Thrones: 9 Crazy Fan Theories About Tyrion Lannister
8. The Sailor's Wife Is Tysha
The Sailor's Wife is a prostitute working in a brothel in Braavos. When Samwell Tarly, Dareon, Gilly, and Maester Aemon stop there en route to Oldtown, she is the woman Dareon beds, leading to Sam leaving him behind.
She is notable among prostitutes for only sleeping with those who marry her, which Dareon does. She is sad to long for her first husband, who was her true love, and also has a 14-year-old daughter called Lanna. That's where this theory comes from. It isn't known how many whores are married in Westeros, but this is one we know for sure was. Secondly, Lanna is a common name for girls associated with House Lannister, and she has golden hair.
That does create some evidence that the Sailor's Wife is Tysha, although somewhat ignores the fact that she wasn't actually a whore to begin with. Of course it's not totally impossible that she turned to this path after being sent away from Tyrion, and it would answer the question: where do whores go?
