Steve does frown a little in thought, because yeah, that sounds... a bit complicated and hard to recreate. Although he does have to let out a small huff of laughter, because, "Well, good think fighting's what we're good at, right?" Even if they don't know how, they'll figure it out. They always do.

Especially if, "Was that - is Natasha actually here?" She's the only person from the fake life or whatever he was living that he still knows, now that he has his own mind back. And the powers she'd had were electricity based. Maybe she'll have some ideas.
