Okaaay, he wasn't expecting that. His eyebrows go up a fraction and Reid gets another long pause as he processes the question in his turn. He does appreciate the directness and he wants to give Reid an honest answer, but it's not a question he's actually thought about himself and so it takes a bit of pondering before he looks back at Reid and says frankly, "I don't think so. There's a lot of mutual attraction there--" Obviously. Reid would have to be blind not to see that, profiler or not. "--And we're good friends. We work together and we've shared a lot and helped each other through a lot. But I wouldn't call it love. Any more than I'd call what I've got going with Spike love."
A gentle reminder that whatever the attraction he's not going to be acting on it, at least for the moment. He's got enough on his plate!
