Is it locked, or one of those windows that are just embedded in the frame?

Embedded in the frame, apparently. 

Well. Breaking it right now would be rude. So she's just going to keep to the wall and feel along it, trying to see if there's any doorway or alcove she can slip into.

There's a doorway after a bit, but just as she gets there, she hears a shout from down the hall. 

She freezes for a moment and then tries to open the door.

Fight them! suggests Little Pummerin. She shakes her head.

"I'd rather not get caught up in this situation!"

The door opens.

The room beyond is much like the one she left, except there's a person in it. A very startled person, who says something in a surprised tone.

There's footsteps approaching her position from the hallway.

Damnit. She curses under her breath before backing out and turning back. Is there anyone coming from the direction of door she came out of?

Nope!

There's more shouting.

Okay. They're probably going to chase her no matter what now. She rubs a clawed hand down her face. Should she just try and talk to them instead of running away? If they have a description of her, they can probably put out a bounty or something. Finally, she decides to just stay where she is for now, holding out her hands.

"I don't know how I got here, but I promise I'm not an enemy of the state." She knows they probably won't understand her, but maybe they'll get her tone.

More words in the foreign language. She might recognize 'chimera' from the documents.

There seem to be orders in whatever they're saying, from the tone off voice. When she shows no sign of understanding, someone hesitantly tries what's probably a different foreign language.

She shakes her head at the word "chimera" when it shows up, although she does her best to express lack of understanding for other words. She doesn't know any other languages herself, but after a bit of thought lays her hand on the wall.

"Hey, would you mind translating for me?" she whispers. "It's best for me to cooperate here, right? So I need to know what they're asking."

The building doesn't really like either her or the people in the hallway, but it'll translate (albeit reluctantly and with much grumbling) since apparently she isn't with its enemies, after all, if they don't recognize her.

They're mostly demanding that she explain who she is and how she got here, as well as who she's with.

She points at herself. "Surolam," she says. At least names shouldn't get messed up too much. There's a pause as she remembers her Pokeballs, though not all her team was with her then. After a while, she unclips three balls from her belt and holds them out for inspection. "My Pokemon," she adds. "Pokemon" should be a common word no matter what the language is, right?

There's murmuring. One of the soldiers approaches her, says "Surolam," gestures, then something in the foreign language, which the building helpfully translates as "Come with me," then puts his hand on her shoulder. Something else, translated as "And no sudden moves." 

Little Pummerin bristles at their presumption, but Surolam nods and goes along with it for now. She taps her cane on the ground as she walks as well, not wanting to trip over any small dents in the floor or something.

She's led to another room - luckily on the same floor - and announced. There's someone else there, who asks questions again, though this time more calmly than the soldiers in the hallway. The building helpfully translates the questions as, "Who are you? How did you get here? ...Do you speak Amestrian?"

She repeats the name "Surolam," again for the first question. For the second question, she pauses before saying "portal," moving her free hand in a circle in front of her to describe the shape of the opening. At the last question, she shakes her head, before pointing to her ears and nodding, then pointing to her mouth and shaking her head.

"I'm Major Miles. I'm afraid I don't understand what you mean by 'portal.' What languages do you speak?"

She holds up one finger. "Shikoku."

"I don't think I've heard of that language. Where are you from?"

A pause. "Shikoku." That definitely sounds awkward. Oh well.

He hums. "Haven't heard of it either. Do you recognize any of the following names..." What follows is a fairly long list.

She probably doesn't recognize any of them, unless they sound similar to Pokemon regions.

Not particularly, no.

(The building gleefully informs her that the fact that she doesn't recognize any of the names is disconcerting the officer.)

"Well, more will have to wait until we get someone better at languages in here. Do you need anything?"

Well, it's not like she wants to upset them. She's just as confused as they are. She shrugs a bit at his question. "Chair?" She's able to mime sitting down pretty easily at least.
