Christian had been struggling since he broke his arm. First of all, he beat himself up over that whole mess and letting Nox get away right after he finally got the first clue into what the villain was up to. The insulin was truly perplexing…unless he knew a diabetic in need. But that wasn't exactly prime villain behavior.
Then again, neither was the stunt he pulled with Inferno. He still hadn't figured out why Nox did that. Was it because he was feeling petty about his date being ruined or what?
As if the confusion over what Nox was doing wasn't bad enough, Christian had broken something for the first time since he was a much more fragile child. Two somethings, technically. His arm and a rib. He didn't tell Avery about the rib though because he didn't want her to worry…and couldn't take the time off work.
