Scott wasn't Warren's patient. Warren ran a business. He was no more medical trained than he was a ballerina. The only healing he did came from his blood, and the only pushing he'd done were things related to Scott's basic level of comfort. Because he was Scott's friend - the oldest living, along with Bobby and Hank.

"Scott has never been the warm and friendly sort. Since his wife was killed he's been... impenetrable. No one can reach him. If he keeps going on this way, I don't think he's going to live long enough for us to figure out how to."

Scott would hate him for saying that and just then, Warren didn't care. Because Warren was his own kind of prickly, uptight, asshole here and there but he was also Angel. No one, but no one, should ever be confused about his codename, and it really wasn't just because of the wings, the arrogance, the capacity for ferocity under fire and in defense. There was also something fundamentally... compassionate and warm in him.

That came out primarily when he wasn't being those other things, but there all the same.
