It doesn't even occur to her that they might be thinking of two different events, that the one he's talking about isn't the one on her mind. Everything he says fits, even the part about getting back to her, though that part strikes her as just a touch off. The rest of it could just as easily be her own point in time and so she thinks nothing of it.

"I know," she says, her voice still soft, yet weighted with emotion. A part of her wants to tell him that he made a noble sacrifice for a world that wasn't even his, but the words get stuck in her throat. So instead, she closes her eyes and takes a deep, shuddering breath to help calm herself and then another and another. With each inhalation, she uses the feel of his arms around her as a weight to ground her in this reality. In this world and everything that comes with it. Slowly, slowly, her fingers begin to relax until she's just holding him normally and her hands aren't wrapped around the fabric of his jumpsuit anymore.

"I know... you can't go back." Not by his own will, no matter what point in the timeline they're talking about. "It's okay... I'm just glad you're here."

She'll just have to make the most of their time together and hope that whoever or whatever is responsible for bringing them here it won't pull them apart anytime soon.
