I dunno, I kinda see Foggy more as having a healing power. Maybe it drains him to heal (to a dangerous level, or maybe it's a case of trying to heal *everything* including genetic disorders when all someone's looking for is for their nose to stop running) and that's why he never explored it.

Healing of course, works through full body contact. Foggy Nelson is - The Snuggler.

Someone's just looking for a nice bit of angst, and here I come, bringing the crack. ...sorry.
