I like the idea behind this! Anyone else have any other ideas?

A fire guy. Manipulation, generations, whatever. It's simple and might not be as interesting as being able to manipulate cause and effect, but it actually fits his character pretty well—especially if we wanna hit that pretentious symbolism nail right on the head. There's this thing called [url=https://en.wikipedia.org/wiki/Wu_Xing]Wu Xing[/url] that's an early Chinese idea that applied elements to emotions and parts of the body. Fire's organ is the heart (you know, burning with passion and all that bull), and Justin's biggest thing seems to be listening to his heart instead of thinking things through. Plus, his main emotion is joy, which in Wu Xing is governed by the heart. Plus, fire is a useful tool but it's also a very destructive force, and somebody that shoots from his hip like Justin might not think that a controlled burn would be better than a dang firestorm. Then's there's the whole "fire as a torch shining light on the investigation of his grandmother" idea. Also, having a fire guy would offer more opportunities for someone like [@Majoras End] to challenge Maddie's fears and weaknesses. Ya know, for easy access to that good teen drama. 

Hell, you already made the duder's color red.
