season 1? i forgot to watch season 1 last four episodes, i reached where serena cannot admit to dan that she loves him but then she does, then i lost my cds that have season one gossip girl, so can someone tell me what happens after that because i'm watching season 2 now and i don't get anything especially why serena and dan broke up.. and blair's boyfriend hooking up with other girls, and dan's sister working so hard during summer for sewing or something like that. anyway please explain with detail but keep it simple. THANKS!!
