David whistled as Ant Girl gave the ma - Keith - a piece of her mind. Looks like she was idea of them being hit by guns very much, but at least they were just rubber bullets. 

Well, it didn't matter to him though. Normal guns wouldn't even be able to puncture his skin. The rubber bullets that grazed against his skin did little to let him worry about his health - although he did worry about damage to his clothes. 

David turned to the twins. "Hey there, I'm David. Since it's obvious you guys are applicants, can I ask if you guys have fought him already? If you haven't do you mind telling me who's going next? I don't want to trouble you by getting in the way," he said with a grin. "I can always go last, anyway. I don't have anything else to do at the moment."
