"They don't have me leashed." Maybe he said that too quickly? Or maybe he said that a little too loudly? But it was true, and just - he liked asserting his independence, even if there had been a time that he had been in SHEILD custody, and been monitored but - not any more. He was here by choice. And not just because SHIELD was an easy choice to make.
He stared down at the pictures, and slowly shook his head. Although - "Well." He kept his own voice low, "wasn't me. Wasn't Natasha." His gut said it wasn't, so. But that didn't narrow the field, SHIELD had many many assassins on the payroll. He then looked up, making like he was stretching his neck. "Think I'll take you up on that offer to visit."
Bucky really didn't think it was SHIELD. But he didn't want to discuss why or why not in a place peope might be listening in.
