Jumping down the small wall that raised the cemetery from the ground, America stuffed her hands in her pockets and scuffed her foot along the ground, contemplating Natasha's concerns. On the one hand, America bristled a little at her abilities being questioned, but at the same time she knew it was a viable worry right then. Her powers weren't what they were and nothing was a sure thing here.
"If I get stuck in-between, the reasonably hypothesis is that I'll regain most of my powers. In which case I'll be able to open up into whatever dimension I want." That was working on the theory that this place wouldn't give her hell for trying to get out either. "I'm not one of those self-sacrificing heroes." She was barely a hero half the time, coaxed into things by others and just going along with it. She did was she thought was best. And this was maybe one of their best chances.
If everything was normal, she'd have no worries at all in what she could do, she wouldn't think about limits at all. But this wasn't normal at all. "I think we should try it," the worst that would happen would probably happen to her, but if it got them out, she was willing to take it. Hmm, maybe she was the self-sacrificing kind of hero. "Maybe a few people, tactical sorts. See what they think. There's no point in asking everyone's opinion yet. Least of all if we're not sure what's going to happen."
