Selvig. That's good. He's the only human on Earth who's had some quality time with tesseract. Even before Loki took over his mind, Selvig had worked on it for months in New Mexico. He'll find a way-- Natasha digs her nails into the fleshy parts of her palms and stops that thought before it finishes. Getting home can never be a certainty in her mind. That is just too dangerous. Here and now, that is all that matters. "Selvig's a good man," she confirms with a slightly stiff nod.

Natasha's eyes light up for the barest of moments. The message sets her mind at ease like nothing else could. Clint's the only one who could've sent it, and he's the only person she trusts completely. He wouldn't use that nickname if things didn't look legit on their end. "My partner," she says, by way of explanation, fighting a smile. "He's an idiot." She scoots back in the bed and leans against the wall, looking over at Rush, looking more relaxed than she has since getting here.

"Think you could do me a favor and get a message back to him?"
