OOC: I assumed as much, but didn't want to assume that Yina wanted my help. That said...
Yossariad nods and kneels in order to get a better look at the wound. When he speaks, his voice and inflection change, deadly serious and highly professional. It's an odd change for the loopy sibbecai. "Hrmm. The bite of a rat can sometimes be infectious. There's no telling where they've been. This might sting a bit." He takes out his healer's kit [Heal +5, +2 bonus Healer's Kit, 9 uses remaining] and works towards disinfecting the wound.
Once finished, he places his hands over the wound [diminished lesser transfer wounds, heals 2 hp damage, Yossariad takes 1 hp subdual damage]. There's a small bit of a chill, and, then, nothing. It's almost as if the wound weren't there any more, and, indeed, it's barely visible. The sibbecai stands, looking a little bit winded, but no worse for the wear on the whole, and smiles. "That should keep you from picking up any sort of new infection, but I can't promise anything on the bite. I think I got it taken care of, but I may not have."
