"It was clear she still was in love with Bryce. " Are you sure about this especially after Sarah kissed Chuck in the previous episode? Just as Chuck is messed up about being a spy, Sarah is messed up about emotional issues (she shut them down because of her profession). She still can't handle her emotions in the next episode as she murdered a clock radio and yells at Chuck for calling the incident a kiss. Sure, she loves both of them but who is she really n love with? Her emotions are really haywire at that point but she is getting a better grip in this episode.
