Walter isn't the only one who's on edge. The entire idea of this is that it's an encounter where something could very easily go very wrong if either person doesn't stick to their end of the bargain...but that sure doesn't make for a relaxed mood. Envy intends to keep his end, he was the one who proposed this after all, but he doesn't trust Walter either. He never trusts anybody just to say that no, they're not looking for revenge after being attacked; when paranoia keeps you alive for centuries, it's not something you let go of easily, even in this world.

He's just hoping that if things do go wrong, that Wrath doesn't get caught in it.

So he's brought a full team of his own, just in case he does wind up needing to fight his way out of a trap. Lilith, Juliet, Lucky, Samus, and Carl are all hidden away in their Pokeballs--Lilith is closest to his fingertips, if only so that he can get her out quickly if one of her illusions becomes necessary to escape. Only Chimera is out and walking alongside the two of them--it's calming just to have him out and there. The big dinosaur is a little worried about this himself, but ultimately? He's sure this will work out, and sure that if things start to go wrong, then he can stop it before it gets too bad. He's done it before, it's the advantage to being so big and so strong. And that certainty bleeds out into even into how he walks and carries himself, giving Envy some measure of grounding as they approach, even when Walter and Assumption come into view. He stops walking towards them from a good ten feet away, because better safe than sorry, and puts a more confident smirk on his face than what he's actually feeling, reaching a hand up to place it lightly on Chimera's side, while the other rests at an angle on his hip.

"Well, here we are, just like we said we would be. Are you ready?"
