[Just romantically walking their dogs together nbd. Except Crowley's hellhound is invisible. Oops. This is probably for the best until the dog gets a little too frisky and picks up a park bench, sending the couple sitting on it to the ground and shaking it invisibly in his jaws.]

Bad dog!

[Crowley rushes over and pulls the dog back by its invisible collar.]

You mustn't mind him. Normally he only mauls and terrifies on demand. [He smirks in a distinctly unsettling way and the couple runs off. Crowley scratches the hellhound's head and turns to Will.]

I know I'm only encouraging bad behavior, but it was so funny.
