I meant that he hasn't shown much of his personality since China.
Yes, those basic ideas are still there, but as I said, everything he says and does (with the exception of the superpower-Tiki-exorcising) could have been done by any other character and it would have fit with the story. Rabi could have saved Rinari from falling, Kanda could have fought Jasdevi with Crowley and run away (if he wasn't dead), and he hasn't said anything really important or interesting, either.
Even when he does show his concern about friends, it seems... hollow, somehow. Things improved this chapter, but prior to that there wasn't any real concern over them except for occasional moments that seemed randomly inserted. The humour is the same way. It's less of his personality than a moment to show that he's still Allen, and it doesn't really work out because it doesn't fit with the flow of the story.
