A guy who has been the kind of his own little CSI-Gotham and he starts to get really jealous of the public acclaim that Batman gets for what he considers to "kindergarten sluething." To prove that Batman couldn't solve some of the tough cases he's had to solve, he would go back through his files and find the hardest ones, and then recreate them.
Very nice!
That idea fits in with my chip on his shoulder angle too.
