When do Chuck & Blair start falling in upendo with one another? Episode au Season??

I think chuck was in upendo with blair from the start around the episode wild bunch wewe start to see it ,and blair falls for him around the last episode of the first season!!!!

I believe that Chuck fell for Blair when they were kids....like Serenate, wewe can see it from the first episode of GG...that he was in upendo with her..now for Blair, I think that she fell (actually fell) for Chuck in around episode 1.08..when it was her birthday party and he was there instead of Nate....that's how I see it anyways.

I Don't Really Know When Blair Fell in upendo with Chuck but I Think He Always Loved Her but She Was Dateing His Best Friend.

Chuck is already in upendo with Blair from the beginning, but Blair starts to fall in upendo with chuck after they sleep together in season one but blair does not admit it till after they slept togather Remember in the beginning of season two when Blair told chuck if he does not want her to leave then he had to say three words eight letters but chuck could not do it. Then chuck told Blair she had to say she loved him to but she could not either. She tells chuck she loves him when chuck should up after he has been crying a lot when she tells him she falls asleep when blair wakes up chuck was gone. Chuck finally tells blair he loved her at the end of season two his exact words are I upendo wewe TO.
