Yes, Captain America is a name, or title, he recalls. Someone vague, a defender of a kingdom he's heard reference to here as the home of many of the people gathered by the portal. Someone that Soldat's HYDRA wanted removed for whatever reason, and as he has no real knowledge of either side he can't possibly judge who is in the right and who isn't. HYDRA's methods he's skeptical of, as clearly Soldat wasn't treated by them the way he would expect military leaders to treat their elite soldiers, but sometimes hard things have to be done in order for there to be justice for the rest.

"I'm sorry," he says, for he can tell this revelation hits Soldat hard. He'll let the mystery of how a sickly artist becomes something far more remain a mystery for the moment. Of course, now he's not sure what else to say either, for what do you say to that? A person suddenly realizes they were set up to kill their best friend, simply because they were on opposite sides of some sort of war.
