It was difficult for him to get his head around. He was more than a little wary about the whole thing but he couldn't let his paranoia best him. He had to look past that and take the chance he was being given. Luke was willing to work with him. Forgive if not forget, It was the way Tenel Ka spoke of the past, the way Mara was...well alright she was less willing to forgive but he understood that. The things he had done to her, the cruelty he'd shown. He'd hated it but...
Though he did not like being lectured. It reminded him too much of their meeting in his tactical rooms on the Anakin. The way Luke had spoken to him then. The humiliation of that meeting. But again, not something he could take with him. "You're willing to trust me. I don't understand it, I have to admit that. But I am appreciative of the chance and I promise you I'm not going to abuse that. I'm doing what I have to here to be the man that my wife fell in love with all those years ago. The man you once had faith in. I'm not going to tell you that I was wrong. I'm not going to tell you that I believe my reasons were wrong. They were the only path I knew to follow but here, in this world I have chances I never did. And so do you. You have her..."
Not a Sith. No, he supposed he wasn't. He still carried that darkness inside him. That would always be there. But nonetheless.
"Lets take this chance Luke. Lets work together if we are able and maybe one day we can be family again as we once were. Deal?" he said simply and held out a hand again, firm in the decision that this was the only way forward. It was the hardest thing he'd had to do in a while, it was admitting to himself that he had a lot still to change and a ways to go to do it. But there it was. He wasn't old, but somedays, he felt it.
