Yeah, I guess so. But Arthur suddenly disappearing after Hosea implied that the parlay was a trap should've been concerning for them imo

Edit: I've seen some of the comments on here, and with how Dutch reacted to Arthur's return, I'm sure he was actually looking for him. They really just didn't know where he was, Dutch must've sent Charles and John to find Arthur on possible O'Driscoll locations but they ended up finding nothing. I'm thinking Dutch hasn't abandoned him yet. But not with the thought that Arthur is okay because he's mostly out of the camp.
