In Love Actually, Sarah is eyeing the affection of her boss Karl, who is played by actor Rodrigo Santoro. The two share a kiss in their Love Actually storyline, but nothing more happens and Sarah ends the film with her mentally ill brother Michael, opting to stay with him over the holidays. There has been no word if Santoro will be appearing in this new scene between Patrick Dempsey and Laura Linney, but if he does you have to imagine Karl and Dempsey's character will be somewhat at odds. Then again, maybe the goal is just to give Sarah the romantic send off she was denied in the first film.
