Haa, well, to him the thought process probably doesn't go, "Watanuki's in danger, but those guys are worried about him and have it handled." It's probably more like, "Watanuki's in danger, I have to do something."
Completely a straight line. Add to it that you're probably the first person Watanuki turns to for most things, it's just a thing that selfishly matters when your most important person doesn't see you that way. Though I'll say it's pretty much an emotional thing rather than him using his head.
