Jack would look pretty amused, knowing he knife wouldn't hit him and standing stock still. When she whispered in his ear, his quiet reply would be said equally as fast. "Nobody said I wasn't being serious." He would look around to the rest of the room. "It seems that our Captain here knows what we're capable of, or else I'd hope she wouldn't have tried to end me. But none of us know each other. So we should start with introductions. My name is Jack. You can all call me Vice."
After he spoke, his outfit would shift and move on its own, becoming skin tight and appearing as though it were a costume. He would look to Captain again. "I'd smile for you, precious, but I'm not so sure you'd like it." He would let the mask slide back and disappear, giving her his real smile, before walking into the training room.
