"Tony," he tries, tapping his foot. "I've got coffee and a grilled cheese and if you don't open up, they're both gonna go cold." He hasn't seen Tony in too long. There's gotta be something he's working on. But at least, hearing him - what Steve assumes to be a message he just wrote - is good. It's comforting.
