Finally saw Robin's backstory in One Piece. Holy crap were there a ton of tear-jerking moments (4 big ones to be specific). Granted while Chopper's backstory made me sob way more (his had 2 REALLY big sobbing moments), Robin easily takes the cake as the most tragic character in the series.
I'm looking forward to the Enies Lobby arc next since I hear just about every character has their time to shine in it. Plus that's apparently when we learn of Robin's backstory.
