For what it's worth, I feel the same, but I also didn't get the vibe that it was her rejection that turned him evil? It seemed very much a signpost but not a starting point. Following along with his (pretty clearly intending treason) father gave me the feeling that we're meant to see both his proposal (at his father's urging) and his later actions against Rohan (and particularly her father) as signs that he does not care about her as a person, just as a symbol. He was evil before he proposed; we just don't know that until some plot and flashbacks provide more clues.

So...how did he get out?

They got out through a one-way secret passage, and then Pops-sicle couldn't get back in once they snuck around to the main doors, due to buffness. Everybody fighting at the doors did, eventually, freeze! Pops is called out as having frozen standing up still fighting, though, so I suspect the others were corpsesicles rather than troopsicles when they reached the freezing point. :D
