B & S have a discussion...during ep.3 of season 2 (my thoughts...no for real dialogue)...Chuck walks in on the scene--shows a lot of vulnerability on Blair's side with need for Chuck and need for passion in general. ;p
B & S fight it out over Chuck, and Blair's inability to let him go...followed 의해 a happy CB ending...and angry James stomp off. Takes place after the tragic makeout scene in 2X03.
