"Pre-med."

"Business, actually."

"Psychology!"

"What, not an undeclared among us? Hn." She is tempted to swat Dylan with a pillow and chastise him for being a basic bitch in his choice of majors but they do not, actually, know each other well enough for that yet. 

How to spin this... eh, maybe the smart thing to do is just let someone else talk.

"I am going to become a therapist and be a gift to all mankind with my intimate knowledge of how to survive having catastrophic emotional problems," says Lenore, very cheerfully.

Score one for letting other people talk!

"All the information about my catastrophic problems is locked behind friendship level five." 

"I respect your life choices! It would be a smaller and less beautiful world if everyone was exactly like me!"

"I'm a fan of her being like herself instead of you." Hug. 

"Awwwwww."

Okay, he can't take much more of this.

If his magic works the way he feels like it should—if it works at all—if the pillowfort counts—then everyone in this fort is going to get gradually cozier and comfier and sleepier, hopefully gradually enough that nobody will decide to leave the fort.

Eliza sighs, muscles visibly relaxing as her eyes slide shut. She makes a contented humming noise and leans closer into her boy. 

Lenore is fully prepared to nap in a pillow fort with people she met an hour ago and will be the first to yawn.

Due to how yawns work, Dylan is now also yawning, which is on one level annoying because he really needs to not let himself fall asleep in his cozy fort, but on another level helps sell the illusion that none of this is his nefarious doing.

The important question, though, is: can he get them all to fall asleep here without anyone getting suspicious and leaving?

Oh look a cozy nap zzzzzzzzzzzz. 

What she said.

He waits until he's sure all three of them are down, and then tries to think.

This is a pretty comfy pillow fort but he's still pretty sure he just verified that he can do magic in a pillow fort he built himself. Good to know. Now he has to verify that the thing about memory modification works the way it's supposed to. So... he should wake someone up, and have something happen that will be memorable enough they'll talk about it later if they remember it but not insane or upsetting enough to get him in trouble if he can't make them forget; and, while he's messing with people's heads, he might as well see if he can get the other two to dream about extremely specific things. He can start a conversation about it afterward to find out if he succeeded.

First things first... who should his chosen victim be? Lenore seems like the one who will take weird stuff in stride the most. The other two should probably stay asleep.

Then, what should he do to her? He has plenty of ideas for what to do to a helpless girl he has completely under his control, but he reminds himself very firmly that there is a time and a place for that sort of thing and the time is not when he's barely begun to figure out how these powers work and the place is not in a pillow fort completely open to the air just down the hall from the mystery suitemade who's presumably still locked in his room but might come out at any moment to grab a snack or go to the bathroom. So, leaving aside any suggestions that could get him arrested, what kind of event can he arrange that's weird, memorable, and mostly innocuous?

How about...

Lenore half-rouses into a sleepy haze to find herself staring at a bright pink feather, which proceeds to start tickling her nose. She splutters indignantly, but her limbs are heavy with sleep and she can't seem to move properly, so the feather has her pretty much at its mercy. Is someone holding it? She can't open her eyes far enough to tell. "H-hey... quit that..." No one is going to take her seriously while she is both half-asleep and giggling. She gives up on her ineffectual protests.

And leaving aside how hot it is that she was that helpless in his power Dylan puts her back to sleep and reverts the feather into the scrap of pocket lint he transmuted it from, then does his best to erase all memory she has of the encounter. Then he tries to plant vivid and specific dreams in Joey and Eliza: for Joey, a dream about rowing across a lake of bubbling, fizzing Coke or Pepsi (the dream neglects to specify the brand) on a raft made of the toast they just ate, and for Eliza, a dream that Lenore revealed she was secretly a were-gecko and then refused to stop climbing all over people with her tiny adorable gecko feet.

Having accomplished all this, he lets himself flop cozily into a semi-doze among the pillows and then wakes everybody back up.

Eliza unflops just enough to confirm that Lenore is human-shaped and not climbing on anyone and then reflops. 

Dylan gives his best sleepy yawn.

"Well, that was not a nap I intended to take." He sits up and observes the sleepy friends. "Did anybody else have totally batty dreams? I was on the run from the law with the Mario Brothers and Luigi kept quacking like a duck."

"There was...a boat? Sorry, I don't usually remember my dreams very well." 

Eliza checks her phone and blinks. 

"...The dream I had wasn't especially unusual as dreams go but I don't usually dream during naps that don't last, like, way longer than that one did." 

"I also don't usually fall asleep in the middle of the day. Magic of the pillow fort, I guess. Hey, Lenore, you awake? Have any crazy dreams to share?"
