"Oh shut up and stop making things worse" Jack spat back at Linn when she responded to his question about the mission, and his eyes flashed a bright orange. She was just trying to make things worse and now she was trying to play apologetic but he wouldn't be fooled, if she can't take the heat then she should leave the kitchen, that's what Jack believed. All he knew was that he wasn't going to back down and let these jerks walk all over him, he would fight back if they tried anything. 

He listened to Bruce ask how they were going to find the criminal they were looking for a and if they should split up, Jack replied, "We probably shouldn't split up otherwise the risk of being ambushed. Wherever this person is hiding, I could probably get there by burning through the walls."

Jack was hoping to get the chance to melt away walls during a mission sometime and now might be the one where he would get to do it. Now the only question was, could this team ever work together? Right now Jack was having a huge amount of doubt.
