Kai has escaped two prison worlds before. I definitely feel like he would probably be able to escape this one too. Lol Bonnie better watch out, Kai looked like he wanted to kill her (or fuck her maybe? Couldn't quite tell)
Definitely the latter. :p
This prison world seems pretty inescapable. This time he’s chained to a chair. Bonnie has the only ascendant. There are no celestial events. And no other entities there besides him. So it would take Bonnie changing her mind about Kai and deciding to free him.
