He's walking briskly; he wants to get to the bedroom quickly and get under the bedcovers.

"Then you're really goddamn lucky I'm the one you decided to screw over, aren't you?"

"Ye-es?"

Here they are bedroom bedcovers brr.

...also he's leaving his shoes by the door of the bedroom because he's really fed up right now and he doesn't want to pretend to be American anymore. Walking around the house with shoes on. Horrible.

"I'm going to teach you how to use a computer and then you're going to figure out the spell you lied to me about which would have been so much more useful than the bullshit you pulled today. And your spell had better include a way for you to leave this house, I've only been around four days and I'm already dying of boredom here. And it had better also give you taste buds, I can't believe you decided to waste your first proper taste in thirty years on a Snickers bar."

This near-instantly grungifies his socks, and the sheets whip up a dust cloud that makes Jeremy blink.

"Okay.  I'll try.  ...There are already untethering spells."

Okay change of plans he will first try to shake all of the dust off, covering his mouth and nose with the crook of his elbow to try to prevent coughing.

"If you open the window I can probably manage a breeze."

Excellent! He'll do that.

Then there can be a gust of wind in here.  At first it just swirls the dust up more, but after a moment there does seem to be less in the room.  (Though substantially more on Jeremy's desk.)  It's not very warm, but it is warm rather than cool. 

Jeremy's panting, when he lets the air go still.

Cool so Jake can close the window then and get under the covers. And keep them lifted and pat the bed next to him, looking at Jeremy expectantly.

Here's a Jeremy.  He looks kinda—dizzy, or something, now that he's at less of an angle to hide his face.

"You okay?" asks Jake, snuggling up.

The covers fall through Jeremy.  "...Yeah, I—yes.  I'm much more able to affect the physical world than most ghosts but within that I'm much worse at ghost things than I am at things a human body can do."

Jake frowns at the cover going through Jeremy. "You're behaving very badly," he tells the cover. "There's a boy here and you should cover him so I can snuggle." He tries again.

Jeremy stiffens at the initial comment but—at least stops doing that, if not relaxes, when it's clear what Jake's addressing.

It feels really weird to attempt to move the cover, given that both it and Jeremy are tangible to Jake but not to each other.  But once he puzzles it out it's not actually very difficult.

".....I—"  The blanket falls though Jeremy again.  "I don't think me trying to hold that up right now would have consequences you prefer."

"No, you shouldn't, it's the cover that's working badly." What if he koalas Jeremy, then the cover will be mostly over him. Come onnnnnn.

Then it drops half through Jeremy, but at least he's technically covered by Jake, and where there's not blanket there can be touching Jake directly.

"This is stupid. You can interact with my clothes, the cover should count. This is making it less cute." What if he stretches the cover so that it's taut over them?

Then it will only intersect what an approximately-flat plane would intersect!

"I need to learn magic to fix this but I'll declare it good enough," he says, adjusting their position so that he's mostly on top of Jeremy.

Now that works, because Jeremy's body holds up Jake fine and Jake holds up the blanket fine.  Jeremy makes a small noise about this but doesn't otherwise object.  "Okay."

Good, good, he can relax, then. "Will I get any words out of you other than quiet acquiescence anytime soon?"

".....There are truth spells," he notes.

"...okay?"

"Given that I... deceived you, and then appeared to come clean while extensively deceiving you again..."  He shifts a little, under Jake.  "You might want to be sure that there's nothing else."

"Oh. Sure, I guess, maybe sometime. Right now I just want to hug you and see if that helps the thing where you think everything will be terrible forever and you're the most wretched of sinners."
