It didn't seem to Tony that Felwinter was that much better off, yet he still could say, "You help people." That did seem inconsiderate to point out somehow, like he wasn't supposed to acknowledge it, so Tony's mouth twisted apologetically and his gaze skipped away for a moment, not looking directly at what might have been missing. Either a flaw in Felwinter's perception, or the people he allowed around him. Or his programming, that he didn't remember anything about, and was such a threat to humanity.
