Senku had the very irritating tendency of trusting and befriending people who had very recently attempted to murder him. It was what Gen thought could quickly turn the rest of his hair white. But he'd just remain a little skeptical for them both, until he could be sure she's trustworthy.

Gen listened to Senku, considering that. Two memories tied to his father. He had a feeling that Senku might even still be mourning him - unlike the rest of the petrified world, Byakuya had lived and died already. He'd never see him again.

"You mentioned three memories, Senku-chan," Gen pointed out, not unkindly. He'd comment on the fact the cave trapped them until they had a heart-to-heart in a moment.
