...that one he'll swap out with a basement-dweller. So as not to alert them before he gets the rest. Swap-heal-flee.

They don't immediately notice.

Next one's also in a cell, and looks in—worse shape.

Heal grab.

After the fourth disappearance people become aware that something is going on.

He's invisible, they'll have a hard time stopping him.

Some people are going to check on you in your room, Contessa osanwës him.

- fine. He teleports back to his room, swaps with the basement-dweller.

There is an urgent knock.

He rolls over in bed and rubs his eyes. 

More urgent knocking!

"Whaaat?"

"Epic? Are you in there?" comes Blindfold's voice.

He goes to the door and opens it and rubs his eyes. "It's the middle of the night!"

She breathes in relief. "I'm sorry—we thought—but then they must've—" Pause. "It's nothing you should worry about. You can go back to bed, I'm sorry to have woken you."

" - is there another big monster?"

"No, no, not at all, never mind. Just go back to sleep."

He does.

And then he gets the rest of them, and then he goes and gets the waterboarded basement-dweller.

They've noticed he's a basement-dweller by then—or, at least, unconscious—and cry out in surprise when the body disappears.

He gets rid of it. He goes back to headquarters and stalks around invisibly looking for excitement.

There is not a lot of it! Doctor Ximenes and Doctor Lira are both blissfully unaware, but the Vice-Director, Blindfold, and a couple other capes and bunches of noncapes are running around like headless chickens trying to figure out what happened.

He should probably just go to bed but instead he follows the Vice-Director.

Vice-Director is in a heated phone call with someone who's calling a bunch of different someones and asking bunches of confusing questions.

Well maybe they should have not tortured people.

The answers to the questions are equally mysterious—probably thinker powers—and don't make the Vice-Director any less irate.

...he calls the Director. He's yelled at.

Definitely they should not have tortured people.
