Sam's world's version of events have a slight frown forming on his face, just a furrow of his brows for now. "A train." That seems so strange, that such a big event could be so different from one place to the next. He guesses that's why they're alternate timelines. "It was a buzz bomb for us. A drone plane directed at the White House, flying out from the Channel Islands. Zemo's. Steve didn't want to- I was sure we could make it." It had been his fault, ultimately. "He slipped off. My sleeve got caught trying to disarm the bomb." The resulting explosion had taken his arm and sent his dead body into the sea, while Cap froze and drifted, but he doesn't think he needs to explain that part.

The next bit of news makes him pause, but he shrugs it off. "Tony's from farther along than Steve and I. I haven't... asked, what happened. It probably isn't good to know too much about my future." He'd known about the buzz bomb, once, but he only vaguely remembers it beyond the feeling that certain things have to happen. But then he mentions the bird and Bucky smirks. "Well, I'm not sure if the bird is psychic, or if it's more that Sam is psychic with birds, but yeah. You do."

His expression slowly evens out to something more neutral again, and he breathes out slowly. "Give him time. Steve will keep looking, but he's- we're good. He can stay hidden if he wants." A pause, and quieter, "It took me a year on my own, to get back."
