Crowley... tends to be that way. I'm honestly surprised he's got friends aside from me at all. [Yes, Johnny, he thinks you're friends, poor naive little angel.] With Crowley it's all about favors, not gifts. Do him a favor and he'll pay you back, and expect you to pay him back for that, and so on. That's how I've kept a relationship with him for the past 6,000 years, anyway. [The angel grabs a spare pastry and begins to nibble on it while he looks over the cake with awe.]
