"Really. I do. Come on." The Winchesters both looked skeptical again. Sam sighed, "Crowley, no. I really think that this would be a bad idea. You said that it was in London, I really don't think that it'd be a good idea to invade on London hunter's territory. You can go to them and ask them for the favor. So I think that you should leave. As... soon as we get you out of the Devil's Trap." Crowley started panicking internally.
"Please!" He shouted, suddenly. Out of pure desperation. Dean's eyes widened, and Sam sighed.
"Please. I need your help. Please. I gave up my entire life for you two idiots! I deserve this at least. Just... Please. Please."
The brothers continued to stare at him for a few minutes, until Sam motioned to Dean to talk to him outside of the car.
"I'm just a poor boy. I need no sympathy." Crowley sighed, and settled into the seat cushion.
