[The long silence that follows leaves Haise to wonder if he shouldn't have brought it up. He can't be completely sure whether the Karna he'd met is the one from Arjuna's past, and that knowledge might come at the expense of his associate's peace of mind. Their story might be old in his time, but that doesn't make it any less real for someone who lived it, and the two had been on opposing sides...

Haise thinks to apologize for his lack of forethought, but Arjuna speaks first. He shifts has weight as he considers that question, folding his arms with a quiet hum. What had Karna said back then? It all seemed rather general and mundane, the things that he recalls]

Nothing all that unusual...aside from thinking I'd feel better if he held my hand.

[As they've established, this was a puzzling sort of notion. Haise had appreciated the kindness behind the gesture once he understood the intent, but coming from his cultural background, it wasn't common for anyone to simply reach out to him in that way]

But we were able to confirm that we'd both been weakened in some manner and were both new recruits. [He pauses then, mentally reviewing] And he suggested we work together, with those factors in mind. I don't know if he's the one you knew... But I'd thought maybe I could prove or disprove it without troubling you with the question.

[Thus the confusion related to offered hands here]
