Special mention to stopping a massively Jerkass Genie that actually forces people to make wishes according to their greatest desires, so that she can twist them around to screw them over. She already pulled this trick on most of the cast, but when she tries it on Martin, she runs into a speed bump because Martin's wish is to know how to save his friends. She knows that he found out how to seal her and tries to tempt him into making a selfish wish, but Martin beats her tricks through Heroic Willpower and wishes for her to be sealed back up.

Diana, whenever she has to save a possessed Martin from something. For someone who is usually the Damsel in Distress, she does a very fine job of stepping up to the plate when necessary.
