It's definitely upset. Greg decides not to push. With a low sigh, he tucks it back into its pouch. This is probably for the best. It's from Homeworld, it may be better not to get too close with it.

Still, as he opens the back doors of the van to go visit the Pizzas, he has to consider... the mirror didn't have to show him anything tonight. It didn't need to try and comfort him with the image of Steven. It didn't need to try and reveal its origin. It had kept so quiet, for so many months, and it decided to reach out to him now.

He looks back, one more time. "Um. Thanks. For showing me. I..." Greg stops himself, shakes his head. He's said enough. The van doors shut, and he leaves the mirror alone.
