"Oh, I'll change it back eventually," Crowley said with a dismissive shrug. It may not have been the first time that he had turned an actual gun into a water pistol, but it was the first time he had offered to change the gun back. That he could remember, at least.
Crowley wasn't really one to worry about silly things like boundaries. "The one and only," he said simply before turning to head into the kitchen to start plundering through the cabinets, in search of a glass. He was going to pour the first bit for him, because he had a feeling that if he didn't it would just lead to him drinking far more than he should. And while he did specialize in getting people to do the wrong things, he wasn't really in the frame of mind to do that to this guy. Not just yet, at least.
Besides. He tended to be a lot more subtle than that anyway.
