[Sonic can't help but grin when he sees Shadow; sure, things don't line up, but this is still the guy who he thinks the world of. Someone he never thought he'd see again, and someone who seems to be doing so much better now than he was. Even if the pieces of the timeline don't line up, how can he be upset when Shadow seems so might lighter than he has been in so long?

The words get an easy laugh as Sonic's eyes briefly dart to look at Shadow's apartment, but he's back to Shadow in a moment as his arms go behind his head easily]

Not even a bit! I just figured you might've gotten a head start on finding somewhere nice to go, that's all!

[He'll gesture with his head though; come on Shadow, let's go into town!]

But come on; I know a good place we can go get lunch and talk a bit! My treat. It's been way too long since we've gotten a chance to just shoot the breeze, y'know?

[He's not going on ahead of Shadow; he'll match his rival's pace, but Sonic seems more than genuinely excited.]
