After the events of Enies Lobby it seems the strawhats have come out on top and they are heading back to Water 7, with Robin in tow.
The question I ask is, will she change? We all know Robin as the reserved, most normal person of the group, no comedy faces; just that knowing smile. But maybe it's because she always felt on edge, like she wasn't really one of them. We HAVE seen a more playful side of her, for example playing with the comedy-trio (luffy, usopp, chopper) when she first joined; but she's as yet shown anything consistent.
I actually believe/hope she will become a bit more… one piece-y. I dunno how to describe it, just more whacky, that anime episode with the play was very funny for Nico Robin's over-dramaticism, and i'd love to see more of that.
She jumped and raised her hand joyfully like the rest of the Mugiwara at the end of the latest chapter, maybe now she's over her childhood trauma she'll be a more open person? More interaction with the other crew members? This fanboy hopes so :P.
