Hi guys, what if the reason behind Kuma's weird behavior wasn't his instinct, but someone made modifications, and built the electrical circuit VP talked about into Kuma, so that Kuma can regain his consciousness.
Given that only VP knows how to build that circuit, and that he doesn't know why Kuma is behaving so weird, this makes VP clones as the only people who can make it, it's true that we didn't see them in Kuma's flashback but that doesn't mean that they weren't existing, maybe VP was able to have one clone before erasing Kuma's consciousness, and that clone is Shaka.
Shaka the one who represents "good" among VP's clones, might have dismantled it the self destruction switch as well.
and the reason why VP doesn't know about this, is that Shaka didn't share those informations with the pank records, just like what York did.
