[He's not really sure... Not yet. Luke has a good idea that yes, they do have different souls - why would Luke's look like a child if the opposite was the case? But there's still some doubt, and that doubt can eclipse any kind of hope a replica might have.
Luke glances at Ion once he speaks - hears that hesitation, that softness in his tone. Ion... probably doesn't believe what Luke is saying about souls, or he needs time to think about it. Luke can't blame him; It took him a couple of weeks before he thought to ask everyone about it. So, he looks at the flower again and speaks:]
Yeah, that's all.
[He wants Ion to stick around, maybe talk with him more. They're replicas, they'd understand each other better than most. But... he can tell Ion wants to go.]
