It's a good thing that Harry was observant! He can be pretty clueless sure, but it was pretty obvious with what Arty was doing there. Good thing that the both of them came back though, any more and who knows what would of happened between Harry and Arty.

With the Furret leaving him alone Harry was free to get comfy again in sitting. He was curious what happened though, James certainly wasn't looking too hot.

"Welcome back.... Did something happen?"
