Lord Rickard's Mother in the Godswood Pool

Arya is said to look a bit like Lyanna and have her personality in a lot of ways. Bran thinks he's seeing Arya at first, but he realizes that that's not correct. The next one though is a naked and pregnant woman who begs the Old Gods for a son to avenge her. She came to Winterfell during the time of Ed Wilde's youth. Probably as a wet nurse to his younger brother, another Brandon who died young. So yes, implied romance leads us to, you guessed it, dunking the long himself.
