Leo's eyes are wild, and he fights to keep anything back that gets even a little close to them. They aren't advancing now, and he knows that's bad, he knows that's fatal, but what is he supposed to do? He can't face-man his way out of a situation where the enemies don't even talk!

And then, Donnie calls out to him with an idea.

Leo glances at what Donnie has in his hand, registers that they need the lighter, and doesn't waste time on any other questions. He pulls the lighter back out of his pocket, then grabs for the hand sanitizer. Time to light up some zombies... if it will even work.
