[For all that Envy's perfectly willing to be an enormous asshole to Ed, actually attacking him...]

[He's already broken his deal to Heather once, and he's not about to again. Even if the deal had been about Alphonse and not Ed, he's pretty sure it would wind up being the same thing in the end. Attacking one of the two means fighting both.]

[And he really gets the feeling that she'd be disappointed in him as well as angry, which is even WORSE.]

[So while his lip curls and his teeth grit, he doesn't make any move to attack. At his side, Lucky senses that tension and whines, nudging and whuffling directly into Envy's ear--although notably, instead of responding to that with a kick or a shove, he puts a hand up and simply pushes the offending dog nose away from his ear with a normal amount of force, following it up with an absent scratch to the big dog's head. All his attention is still very much focused on Ed.]

So you're assuming I'm just going to let you skip along merrily next to me with no problem. What the hell's the last thing you remember?
