[Castiel just nods slightly, at her thanks, but at her question he gives a small frown. On some level he's insulted--offended, really--that she would ask him to do a favor for her like he should ever bother, after all that had happened. On another he's offended for Crowley's sake, both for everything involving his death and for acting like Castiel had that kind of control over him in the first place. Sure, if he asked, Crowley might indeed back, off, but...

Castiel is still neutral when he responds.]

Crowley is not an attack dog that I can call off. He is a being with justifiable reason to be less than sympathetic in regards to this.

However, he will not seek you out in person. If you desire not to speak with him, simply cut communication.
