It was probably a hasty decision to just punch Kal like that, and might not lead to good things. But Terry was rash, and hot headed. Not exactly known for thinking ahead when it came to the people he cared about. He needed Bruce, relied on his advice and guidance. Kal had successfully baited him. Kal had drawn him out of his comfort zone and now he'd have to answer for it.
A smirk returned to his face, a cruel one but one none the less. "Terry McGinnis. Don't forget it." There was anger in his eyes behind that mask. Kal was a threat. Had talked about hurting someone he loved. He deserved to be knocked on his ass. So why did Terry feel a hint of guilt seeing him with so much awe. He looked just like Kal. His friend..he wanted his friends back, if he hurt this one. Would it affect the other? Terry lowered his fist without so much as a wince despite the hard contact fist to face.
