Well, it really threw Zero for a loop when Citrine refused to use him as a shield in the Lion/Sea Witch game because even though Zero knows Drift doesn't like him hurting himself, he saw protecting the teams as an entirely different scenario. So Zero was both trapped by the inability to protect Citrine and the realization that Drift was going to take on more pain for HIS sake. Which really really messed him up because THAT'S NOT HOW IT'S SUPPOSED TO BE. But... he also is team-topped so if that's how Drift wants it, that's what he has to accept. Even if he's totally fine with dying for a good cause.

And then Drift got hurt in Riful's heart and is sort of crushed him because again he couldn't protect him. So he felt really GUILTY about the cake but took it anyway because clearly Drift put a lot of work into it and it meant a lot to him. But yeah, Zero is like I DESERVE NO CAKE. Zero has problems...

Drift's hints that he's distressed also trouble Zero because Drift clearly cares about him but won't let Zero ever worry about him. :( Zero wants to help the bunneh.

Reverse~!
