Steve didn't hesitate.
Ending the call, he said, "Sorry, guys, gotta go." Ignoring the confused look on every face in the room, he strode across the room, took Bucky by the arm and steered him out of the kitchen.
"I'll call you later," he tossed back over his shoulder.
A silent Bucky at his side, Steve was heading for the elevator, but something, some innate instinct, stopped him and he swerved toward the stairs.
"Steve?" Bucky asked quietly.
Steve shook his head. "I don't know, man."
The two disappeared down the stairwell. After a few seconds, they both started running.
