Jack would look a bit more downcast as he realized he'd upset her. "I was just... That's not what... I'm sorry.." He would say a bit quietly. The last thing he had wanted to do was upset her, and he hadn't meant to bring it to such a subject. "I just kinda meant how you would have shadow creations and mine would be speed lightning and stuff, I didn't mean it that way. I'm sorry." Jack would take her hand and squeeze it a bit softly. "Besides," he would whisper to her, "I would give you a piece of my shadow before I ever let something like that happen."
Noticing the new guy, Jack would put on a happier face for the moment. "Hey! My names Jack, or Vector, if you like. We're just getting used to the school, thought about putting in a little training. And yourself?"
