In #28 & 29, he's even more bonkers, but I say that as an Amazon fan knowing that on their own, the Gigi and Gaga are basically just cool-looking jewelry; combined is where the real power lies. Not to mention that as long as you have one, pretty much anybody who knows the back story will be after you 'til the end of time. This arc also saw him getting his power-up card from Narutaki, a plot development that's still pretty hard to explain (and after this movie, nothing's changed there. I'm pretty sure Daiki's still using the old Kamen Ride Diend card anyway. My fan theory is that the card just gave him some new tricks, Illusion & Barrier, etc., but I dunno)
The last two are confusing enough as it is, and (along with the trip to his own world) another look into how emotionally unstable he can be at times; see his almost-teary-eye "only I can destroy you!" bit with Tsukasa. And then of course there's that ending, though with the re-aired episodes chopping out the face-shooting bit, it's hard to know what actually has happened anymore. On this one, I'll vote with my wallet, and say I still consider the original ending to be the real one until Toei's marketing department says otherwise. Given that books published post-re-airing still refer to it (Yuusuke turned bad; Diend's headshot, etc.) you gotta wonder.
