Assassin’s Creed III: Liberation for the PlayStation Vita will feature a new female assassin by the name of Aveline. While the game doesn’t follow the same storyline as Assassin’s Creed III on consoles, there will seemingly be some sort of connection between the games.
I could be wrong, but there was a Video where they mentioned that she would end up doing a mission with Conner and you could replay the mission over using him or maybe you will play that same mission in the main game. I don't remember.
That day cannot come soon enough.
