Nash is still getting used to the the routines of this place and taking stock of its perimeters. That's how he comes upon Daryl, caught in his own trap. Well, that and he followed the sounds of swearing, as one does.

He lets out a low whistle. "Do you need help?" It's not really a question— the man is obviously caught in some kind of trap.

By instinct, Nash reaches for his own knife, the one he keeps on his belt, and then remembers that they haven't let him keep it.
