"I won't, you can say whatever you want." Clint got his phone out and pulled up Steve's number. "I'll get him on the line, tell him what's going on, and hand it to you okay? Is uh, different sort of thing." he held up his phone, "Kind of like a phone, but it's wireless like a walkie."
He called Steve and talked to him a moment, making sure Bucky could see him-both so he knew how the phone worked and so he would have less to be skeptical of. Once he'd gotten Steve up to speed he handed the phone to Bucky.
