Awkward attempt to comfort: shoulder pat?

Room, door, hospital.

...okay, shoulder pat, sure.

Scott?

Scott is apparently in serious-but-stable condition. He's not currently receiving visitors.

A familiar face seems to recognize them, though, and comes over.

"Is everything alright?"

"...no. My mother's in a coma and the doctors don't know why."

"Oh god. I- I'll take you to Scott. He might have an answer."

She leads them to a pastel room with a single bed in the center, and a large window.

The occupant sits up, wheezing slightly.

"What happened?"

"His mother is in a coma. I'll leave you boys alone. I'm so sorry," and with that, she's gone.

"Okay, I really want to hear your excuse for this. You were supposed to save her."

"I don't know what you want me to say. I took the wound, what else was I supposed to do?"

"He took a shot for her, Stiles, we couldn't possibly ask for anything more—the doctor said—what else do you know about the knife?—here it is, by the way," he says, removing it from the makeshift sheaf he'd been hiding it in on his back.

"The trade is usually pretty exact, but it can do injury and disease that it can...point at. If there was already other damage, that caused the coma...I could try to take that."

"...wouldn't that make you fall into a coma, too?"

"Not 'too', if it works." 

"Are you...offering to hold her coma for her?"

"Thank you but I will not accept this offer—you're worth as much as she is—we're gonna find a third alternative."

"There's not as much I can do for you guys; if it works, you'll still have three brains to work with."

"If it works. Otherwise we're down two. And anyway, then the knife will be pretty much out of commission, since I don't think anyone else is as trigger-happy with it as you are."

"I guess so."

He winces in pain, and leans back.

"Also that is very much not how the maths works, if my mom wakes up from the coma and you fall into it that's zero sum, we're not better than we were before. Where's Deaton?"

"Who?"

"The one with the umbrella. He didn't introduce himself?" 

"Not really. I think he's used to skipping that part. He seemed fine, I guess. Went home when he saw I was conscious, told me to call him...apparently I have his number."

"Okay, we can call him, then.

"It seems out of character for you to have killed the previous owner of the knife."

"He what now?"

"He was using it in the other direction. I noticed. He wouldn't stop."
