Hmm.

Does she have any hope of just climbing up there...? No, not really. And she can't get an angle on any portalable surfaces through the ceiling hole, either. But she's standing on a portalable surface, and there's a lovely portalable floor behind her, just a short walk and a long fall away.

Boop. Boop. Wheeeeeeeeeeeeeeeeeee.

Boop continues not to be the actual noise the portal gun makes but the logic is sound.

Up she goes and the floor around the hole is portalable, as is the wall around a door frame higher up...

Boop boop! Ooh, is that that catwalk way high up above the floor of the big room with the pillars?

It is! It is that catwalk! With a door at its end.

Gosh. A door.

And then a corridor which bifurcates: to her right there is another door, and to her left it continues on for a bit then turns right.

Hmm... she'll try the door first.

Locked.

Yes but how locked exactly.

Not incredibly locked. Just regular locked.

Let's see what's on the other side, then.

Broom closet!

Why do they lock all their broom closets around here.

Okay, other direction.

To her right there is a little alcove with windows showing the... vast emptiness beneath... as well as a passage/bridge thing leading to another room up ahead.

And there's a door that leads to this bridge thing!

And does the bridge thing lead to a giant broom closet by any chance? No, if it did the door would be locked.

Nope, it leads to an Aperture Science Material Emancipation Grid. Unenhanced.

Not anymore it doesn't.

And what is on the other side of the ex-emancipator?

A machine of some sort. Except...

"Well you found me. Congratulations. Was it worth it? Because despite your violent behavior the only thing you've managed to break so far is my heart. And several Aperture Science Material Emancipation Grids. And a wall."

She blinks up at the - person??

"I didn't want to find you," she says. "I wanted to leave. I still want to leave. With my unauthorized equipment and all of my teeth. I wouldn't even necessarily object to solving your puzzles if it weren't for the insistence on walking through those Emancipators in between!"

"You do not have authorization to take unauthorized equipment with you. You do not have authorization to destroy vital testing apparatus. You do not have authorization to leave. And now I have a surprise for you. Deploying surprise in five, four—" And then a sphere of some sort falls off the person, causing the lights to briefly dim. "Time out for a second. That wasn't supposed to happen."

"...are you okay?"

"I'm fine. Do you see that thing that fell out of me? What is that? It's not the surprise. I've never seen it before."

"I, um, I normally tend to think that people with parts falling off of them are probably not fine."

"Well, never mind. It's a mystery I'll solve later. By myself. Because you'll be dead."

"Nnnnno," says Sable. "No, that is really not going to be the thing that happens."
