[Hank's smile doesn't go away, exactly, but it does turn incredulous, maybe a teensy bit condescending. He sits up a little straighter, holding his hands up, palms out, placating.]

Hey, no harm no foul, you saved my ass, Sumo cleared out the creepy woods a little for you so you can go back to whatever the fuck you were up to without so much shit blocking the view - it all worked out. No harm done, right? Unless you were planning on building up an army of the undead out here so you can go storm the fortress of weird, in which case, uh. I'm sorry my dog stole all your soldiers?

[In other words - no, Sumo's not getting a leash. Finding a leash and getting him used to it sounds like a lot of work.]
