Nymeria recognises a familiar smell from the river, wades out and pulls in Caetlyn's body and won't let other wolfs touch it, but leaves her there.
Later Caetlyn is seen heading a group of Northmen survivors. (I hear she is brought back to life by that guy who does such things) They are captuing any and all of the Frey line, and once confirmed Frey by Caetlyn, who has no voice box left, the Freys are executed, usually hung. I don't see any mention of any of this in the Show, so I am assuming Caetlyn is dead on TV.
