I liked everything but the flashback within a flashback stuff which just seemed to be wasted panels :B
At least the whole reason why tobi was acting goofy has been cleared up now. I never thought it made sense for someone as serious as who he is now to just pretend to be all derpy just as a disguise.
So I'm guessing that the doll that obito wore was the real "Tobi" and that's why after Deidara did his huge explosion we start seing the real mastermind's personality. The tobi shell must've been killed and obito regained control/decided to take control of his body again which expalins why Zetsu tells Akatsuki that Tobi died. Also you see him getting dressed here like everything he was wearing was blown up:
