[The smell of blood and dirt and sweat are unmistakable. Isaac doesn't really close his heightened senses off like Scott does, and he catches the scent strongly as he's heading up from his room on Level Five. When he steps out of the stairwell it's easy enough to see who the scent's coming from: the muddy, bloody, exhausted-looking guy with the military pack and rifle who looks - under the grime - like Dillon (not that Isaac really knows him but he's never looked like this) but also like absolute hell. Getting a little closer - speeding up because wow, dude, what the hell happened to you? - the scent gets more complicated, notes of gunpowder and grief and fresh antiseptic and bandages and raw wounds underneath.]
spam; after someone else presumably gets him to the infirmary!!
Whoa, dude, are you okay?
