John is seeing to some tests when the door hisses open. He thinks it's Ratchet, so he doesn't look up right away. The voice, though, that aching rattle of a sound, does draw his attention. He wasn't able to really make out the words in the distance, but a body sagging against the doorway is more than enough to get him away from the counter upon which he was studying samples under the computer microscope. He does run over, though it's not far to go.

"Kirk," John remembers halfway along that he's forgotten his revolver in his drawer at the flat. Nevermind, though, because he's going to need both hands to brace this body up. He's strong, but he's shorter than Jim. Once he's close enough, he gives a quick glance over Kirk's shoulder, down the hall, to make sure nothing or no one is following. It's hard not to spot the tear (but no blood), so John will attempt to get an arm around the other's waist and have the man lean against his side instead of letting him fall right into the doctor's arms. He'll pick the other man up if he has to, but if Kirk can somewhat walk, that's better. The distance between the entrance and the equipment may seem miles away, but it's only a dozen meters or so in reality.

"What's happened?"
