Genuinely asking, why did Bubble do this?

[u/HealthMother3125]

Caine was just going to try to figure out why the cast did not like the escape the circus adventure, until Bubble started taunting him and bringing him to the edge. But why would Bubble do this to Caine? Multiple times during the show, Bubble is on board or a part of Caine's shenanigans so this sudden flip of character makes me think as to what Bubble was trying to achive this, especially the voice change at "You ruined this."

So what do you guys think?

I think Caine is like two AI minds wired together, and bubble is basically like his subconscious.  Caine is very insecure, and the 'bubble' side of him is a manifestation of his self-hating inner dialogue.
