I love that the first episode of both the first and last season ended with Jaime and Bran.
It's portrayed as a tense moment, which it is for Jaime, but I think new and improved Computer-Bran is too "above it all" to have ill will toward Jaime and he just sees the strategic aspect of this person helping them in the trials ahead.
Plus Bran told Sam he was "waiting for a friend".
