I think this solidifies that Jimbe won't be a Strawhat (and thank God as the apparent only Jimbe hater). His character has been called into question, he's losing a body part, and if he loses an arm he can no longer be helmsmen, but ultimately he's been seen as very weak. All of the strawhats, have had their character questioned (Zoro, Ussop, Sanji, Nami, Chopper, Robin, Franky, Brook) and they have all become stronger for it. Where is Jimbe going to go from here? To a lesser crew at the cost of a body part? He's going to go back to Fishmen and lead, he has no place in the Strawhats and he certainly doesn't fill any role. Monet is a better choice as an astrologist (they need to go to the moon eventually? (I mean Oda has lead to that at least) ). Who knows. Just glad Jimbe is out of the picture (I'm sorry I don't like him but I just don't).
