[An hour and some change feels like an eternity to Bucky. He uses his cell phone seldomly, wanting to preserve the battery as much as he can, in case Nat tries to contact him for more info. Instead, he paces in a circle, feeling the walls with his human hand, sometimes knocking on the metal with his vibranium one, trying to get a feel of the thickness of the metal trapping him there. There's something strange when he taps on it, feeling as if the echo isn't echoing as it should, and it's what's been keeping him from trying to truly punch his way out.

When he hears Nat from the outside, he can't help but let out a sigh of relief. He knocks on the wall so she knows exactly where he is in the silo:]

Hey Nat. I can hear you. [He frowns when she mentions the explosives:] I guess it's a good thing then that I didn't punch my way out.

[There's a huffy chuckle that escapes his lips, even as he thinks of the few cases him and Sam have been on lately:]

You mean this is not the result of my wonderful and charming personality?

[He'll have to check with Cap about this, because they've been rattling a lot of terrorists' cages lately, and he wants to make sure Sam knows to keep his guards up. And to look after Sarah and the boys.

He's feeling less panicky now that Natasha is there, and maybe he does breathe a little bit easier: he knows she'll be able to let him out quickly.]

Thanks. Be careful.
