Caine switches around very quickly between Ringmaster, Red (himself) and Blue.
Ringmaster is active by default, unless something goes out of control. Like Pominai in distress
Blue activates when Red is becoming too much and overbearing. He shuts down any empathy and sets them back on their routine
Caine doesn't have DID - he has his own AI version of something similair. Its not a response to his distress, but rather him flipping through options on how to prevent another abstraction.
Pominai obviously gets a special treatment from him and extra attention - being last human. He tresures her a lot and if she is out of his sight -he will start looking for her.
He was alone in the circus with abstracted for around 4 years, so his behaviour is extreme. He can't allow new guest to be lost, so he would try anything
Aaaand of course, I am sprinking that a bit of a showtime yehehehe
