So it looks like Gabriella was just being paranoid when she warned them about going after the succubus. They beat her easily and apparently with no repercussions. They owe her a big “I told you so,” when they get back.
Now they have a line on the princess. Is she bigger and badder, or does she have her title because of the luck of birth? She does hang out with a better class of bad guys too, so they might not be able to catch her alone as easily and gang up on her.
