As he listens, Envy tilts his head to look at the arm now that Wrath's holding it up. He doesn't actually know very much about the way different automail looks, but this one definitely does look familiar.

It's a nice surprise, to hear where Wrath had gotten it from.

"She did? Knew I liked her...I met her here, once."

Well, he met the other version of her anyway. But she'd always been decent to him even after finding out who he was, and by then he would have been hard-pressed not to be in return. It's good to hear that Wrath had been able to have someone treat him well even in Amestris.

"...I do think I recognize it."

Did Wrath manage to get hold of yet more of Edward Elric's limbs? That would be kind of funny too, honestly. And it doesn't seem like a bad thing to keep things on the lighter side if he can, at least for the moment.
