Permissions: Scent

That huge nose of his isn't just for show. Wolverine is noted for having an extremely keen sense of smell (on top of keen senses in general). His sense of smell is so good that he can basically walk into an empty room and with a bit of deduction, work out who has been there and what they were doing. (It's kind of ridiculous how it works, but he also has metal bones, so whaddya gonna do?) In general that means when interacting with people in person, he'll probably be able to pick up on any lingering scents they had. Things he might pick up on are:

-What they've eaten
-The kind of activities they do (working out, working with metal, having sex, etc)
-People they are around a lot
-Places they spend time at (like All Passions might leave a lingering scent different than the smithy)
-Animals they are around and keep
-If they're nervous (causing perspiration)

And so on. Since this obviously is something fluctuating all the time, you might give some broad ideas here on what Wolverine might pick up on. If you're tagging with him, helpful hints on recent stuff would be cool too. Thanks!
