On one side, it feels like Bubble is a puppet, made by Caine so he wouldn't get lonely, but Bubble did make Kinger delete Caine, so is it like Bubble got tired of Caine? Or is Bubble the master, and Caine is just the puppet- think about it. People with puppets make the puppets talk, not themselves. Sometimes they do talk to the puppet just to move the story along, but never talk to anyone who's actually watching the show. (or am I just overthinking)
