Something happens anyway!

"- hello? Uh - did you maybe do this out of order -" He peers at the circle.

"FUCK." She whirls to her feet, her eyes darting to the door and the vent and the weak points in the walls. She pulls a couple of knives out of her silk dress, and tosses the shorter one to him. "Be very ready to kill shit," she says grimly. 

Something starts ominously oozing under the door. She recites a short poem in Greek and it bursts into flame. 

"What the fuck?"

"This is the Scholomance, do you know anything about the Scholomance?" He speaks English so probably he's not from some ancient Hindi enclave that yote themselves into the Void on purpose but that leaves loads of options.

"No!"

"Well, we're not supposed to have multiple people in our rooms after curfew, so if that happens the school starts sending mals after you. Too many mals." She lightning-zaps something with too many legs that skitters through the vent while something larger presses against it from the other side. "Probably neither of us survives until morning but I'm not giving up that easily." 

"I'm confused but also, importantly, indestructible, would you like me to step into the hall and revisit this bewilderment tomorrow morning?"

"--Indestructible? Uh, that's gonna be--worse--if you're really confident I'd be grateful but--yeah."

"I'm not as confident as I would like considering how confused I am. Maybe I can just -" He interpolates something sticking a limb out of the air vent.

The limb dissolves; the thing screeches and yanks backwards, acidic blood pitting the wall. 

Something intangible floats through the door; Lucy hisses a killing spell in Basque and it shivers and dissipates. 

"You speak modern English, I have--hypotheses--about where you came from but I don't, uh, have any idea which if any is right."

"Is this a good time to have this conversation." Something under the bed exposes itself and disintegrates.

"Well, you see, some of these hypotheses suggest you might have some kind of stimulants on you and some do not." She frags another insubstantial thing, this time coming through the wall next to the door. 

"Do you have a preferred brand."

"You don't really have the slack for those here."

He guesses her weight and offers her a patch. "Slap it on your arm and you should be good for a few hours."

She slaps it on her arm. "Thanks." She kills something gooey; it shrivels up. "Sorry for whyever you're here."

"I mean, it's at least interesting, I'm just hoping I can keep you alive till this stops happening." Does fire work on the insubstantial kind. He can do fire.

Fire does not work on that one but Lucy gets it with a wind spell. "I appreciate that, I am very in favor of surviving the night."

"How long can you keep doing that, because I can try the hallway, or you could send me home and re-attempt this later on."

"--Probably not all night, if sending you home and trying again later is an option then I love it."

"I don't know if it'll work twice, is the trouble, since it would sure be weird if you were the first person to get it to happen if it were easy."

"I have a void affinity."

"I don't know what that means. How about I tell you how to get rid of me, I sit in the hallway, and I will appear a flashing siren in your room to ask you to do that if anything I can't deal with seems to be eating me?"

"Sounds good."

"You just concentrate for a minute by the clock on getting rid of me, sending me home, whatever frame suits you."
