Splitting up could end badly... for him. Holiday was confident that she could get away or at least wound an attacker. Hawkeye was more of a liability for this sort of thing and splitting up would probably cost him his life, but it could give her time to find something for Punchy and AndrAIa.

Biting her lip, Holiday nods in resignation. "Just be careful," she tells him just as quietly, but still sternly.

Then again, he could be plotting to get the jump on her. If that's the case, let him. It would make some guilt go away.
