Daredevil: I'm going to sneak into the side and take out the goons in the back. It'll take me 15 seconds to take out each one. So, you just wait here until I've gotten all 10.
Jen Walters: Uh, I'm not gonna sit here for a half an hour while you pick off goons one by one.
Daredevil: That's not how that math works out.
Morris Walters: Uh, Jen, that Hawkeye guy, what happens to those arrows of his? I mean, does he go around and collect them when he's done?
Answer: This is answered in the second episode, where we meet Ched who's clearly not a genius. Given this first episode was originally written as the penultimate one of the series, and tweaked as the premiere later, it makes more sense why that line might be a throwaway by Bruce, given if it was episode 8 as intended the audience would already have met Ched and understand how he's not being remotely serious.
