She waits for someone else to come to the final room.

"It took a while to find this door, that means there's not a lot of them. I'll just wait until someone comes and opens it for me. Whatever. I'm not up for any more adventures."

Eventually Jen started walking in circles to entertain herself. The discovery she made along the way was that an another meal & water tubes station was present inside, so the wait could techincally be endless. Many thoughts managed to pass her mind during her wait. where on Earth could this place exist and under what circumstances could it be possible, but her only conclusion that made zero sense (the rest were lower than zero) was a secret military experimental base from a conspiracy theory that would totally put a huge budget into a single-specimen experiment.

As Jen was about to brainstorm the fact that she never felt an urge to evacuate her wastes, she heard human steps.

"Anyone there?"

"Yes! Hi! Is this exit?" — a young female voice said. The tone was soft and friendly, but the crude accent that Jen could not identify immediately told her that English was not her native tongue.

"Yes it is. You got nothing on you?"

"Uh... yes. I want to go." — The foreign girl gently pushed Jen's shoulder, but the blind lady stood still, blocking the passage. — "Please?"

"What's your name? I'm Jen."

"Rimma. Can I..."

"See, I got a problem. This blindfold, this thing... It is sealed."

"...sealed...pechat...zapechatana...Yes?" — the girl whispered, stopping her semi-diplomatic efforts to get past to pay some attention.

"Sealed, locked, won't come off. Tried everything. Can you... please... try to get me past this door with you. Together. Okay? I want to go home."

"What if it don't let us?" — Rimma asked.

"We're going to try. Yours sails are set, but this is my only hope. You got there by trying hard didn't you? You didn't surrender, you didn't just accept your fate?"

"Our kind never surrenders. You are right, let's try to go together." — there was a tone of mistrust in Rimma's clumsy pronunciation, but Jen was glad that she did not have to fight to get her plan going. Jen stood aside as her new best friend turned the knob. The door opened, and Rimma gasped and said:

"O Gospodi."

Jen did not understand what that meant, but leapt at her, pushing both of them into the unknown beyond.
