That's more of a surprise than anything that's come out of Alphonse's mouth so far, and considering he just said he was going to give Envy a legitimate apology, that's saying something. Envy's back straightens, and for a moment he's actually, for once, lost for words.

But only for a moment. It is Envy, after all.

"I--alright."

He snorts, because he has to recover from that somehow, and snide humor is always a good recovery tactic. But at the same time...he doesn't go nearly as sarcastic as he could have, or would normally. This all feels bizarre and jarring, but it's happening.

"Just this once, I think you're not wrong to."
