With the help of Natasha and some of the others, they've managed to reboot the systems and get the code working. It's something she wants to learn for another time, but right now, she can see that someone inside is waking up and the water is draining. Peggy is glad for the other people helping, so she assigns herself to a tube with a woman inside wearing scrubs like her own (which she's wearing now simply because she'd wanted something efficient for the mission).

Prying open the tube and being grateful she doesn't have to smash it open, Peggy stumbles backwards when the force of it drives her a step or two back, but at least she's able to help free the woman (whom she's never seen before). What on earth has been going on down here? And is this where they've been all along before they arrive?

"You're all right, you're free," she promises. "Are you okay?"
