Anakin took a moment, a long one, while they talked. It was a lot to take in, especially considering, well, everything. While he hadn't had a family, exactly, as a kid, he HAD had his mom when he was young, and she'd been everything, and then he'd had a big brother and a little sister even when the rest of the Jedi wouldn't have approved of Anakin thinking of Obi-Wan and Ahsoka in those terms.
He took a moment to be grateful to all of them right now, because, honestly, he didn't know where he would be at all if he had just had the traditional Jedi way of going about things to look back on. He wondered, actually, what his mom would think now, and what Obi-Wan HAD thought of Luke. He'd have to ask him about that later one someday.
He smiled at the scene going on there.
"So. This is amazing. I never could have imagined anything like this when the force told me to look at the internet today. I'm glad that it did. That we'll have you in our lives now, Luke. And I have no idea about anything about you, but, you'll have to tell me stuff, okay? We'll find stuff we can do together. I bet there's SOME stuff that'll overlap. Maybe for all three of us." He added, giving Padme a smile.
