Clarkie wasn't going to pretend to think he knew how long it took for Arthur to get what he needed. All he knew was they didn't want to stay in one place too long lest someone notices too much about them. The last thing he wanted was for them to escape one hell hole and put into yet another of their own doing.

"Does it? If you need longer, Arthur..." Clarkie paused. "I want you to get what you need, so we can stay longer." After all, they would have at least a few hours on the road even WITHOUT them doubling around to make sure they're not being followed.
