"Last warning."

She has been wandering away from where it looks like she is for a few seconds now. "I understand you're just doing your jobs, but trillions of people have recently died, did you hear?"

They roll a grenade in.

"There's just no talking to you," she says, and she dismisses the illusion they're trying to grenade and moves on into another room looking for where Carol may be.

The grenade is tear gas, if she stays long enough to learn that. The facility lights go out a few seconds later.

That could hypothetically be mildly useful if she decides to light her way, although she does still have Elf-quality vision and infrared's enough to be getting on with mostly.

Unsurprisingly it seems like going through doors won't land her in the containment cell. Probably the containment cell does not have doors.

Yes, she's hoping for a suggestive wall.

Lots of walls. None of them obviously reinforced against terrifying amounts of power or anything.

Floorplan? Opening mechanism?

There are floorplans on the walls of some rooms! She doesn't even need illusion light to see them, they're lit. They direct her on how to exit in the case of an emergency. There are stairwells, apparently. Every floorplan is incomplete, showing only the nearest safe exist from that room, but if she bounces around a lot she could maybe put them together. 

Sure, she'll do that.

While she's doing that someone turns on the fire sprinklers. Also, if she doesn't still have the alarms baffled, they're trying to talk to her.

Aaaand the facility is shaped sort of like a horseshoe. Maybe around a lot of dirt but maybe not.

Alas, she has not considered the possibility that the alarms might switch to providing information. She pieces together the horseshoe and tries the middle.

It goes.

Carol Danvers lives in what must have been a nice apartment before becoming occupied by a superhuman in solitary confinement who can dance, and express various non-dancing emotions, like no one's watching (because the escape of information could be a catastrophe by unclear causal mechanism). She's very surprised to see Loki.

"Hey. Someone just murdered half the universe and a precog says we need you to fix it."

...Danvers manages a bewildered nod.

Loki jumps them to Wakanda.

" - well, hello."

"Do not drip on my lab," says Shuri, reaching around for a towel and throwing it at Loki.

"Sorry." She towels off and teleports the puddle away.

Carol is out of practice with talking to people and looks around, not saying anything.

"Hi, Empress! Did Loki catch you up on everything or is there more of that to be done."

"We didn't converse much," Loki says.

"The Kirby games went really downhill after Epic Yarn," blurts Carol.

"Did they just leave you alone in there?

Wow.

Well, this just gets more and more fun to explain the more times I have to do it, so here goes. There are these magic rocks. They look kind of like the plastic gemstones in plastic necklaces someone flings off a plastic float at Mardi Gras, except they make you omnipotent. There's this big purple fellow with too much chin, collected them all, killed trillions of people. We have a plan to stop him. It needs you. It involves enormous amounts of horrifying destruction, so it's actually great how that's a known side effect of you."

"Why didn't - you get me before he did that?" Carol asks.

"Ran out of time. The guy with the plan figured out that we needed you about twenty minutes before he pulled it off, and we were on another planet."

"But she -" Carol gestures at Loki.
