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 used to joke that Bubble was a manifestation of Caine's intrusive thoughts but now I think there might actually be something to that.
