Envy doesn't really follow other people's conversations on the network much anymore, unless there's a pressing reason to or the gossip looks interesting. He has better things to do with his time.

As far as he knows, there haven't been any pressing reasons.

Maybe after today he'll start paying attention again.

But for now, he is blissfully unaware of the presence of That Fucker Roy Mustang in the world, and is just walking down the semi-crowded street with his Lucario and carrying a plastic bag of "groceries" (read: sugary cereal, cheap candy, and pokemon treats).
