I thought that "A Broken Heart" was good - the Syd-Anna fight at the church in Malaga and the missions in Morocco and Sao Paulo made for some good action, but the moving moment with Sydney and Vaughn at the pier (where Syd breaks down and cries while telling him about the loss of her friend and contact in Morocco and how Jack stood her up for dinner, then makes her first connection with Vaughn by putting her hand on his) was what made the episode.
