Whatever Lust was going to say on the subject of complicated centaur costumes and the likelihood of it being enjoyed by her audience is forgotten immediately.

Your Amestrian friends drugged me.

She manages to mostly choke back the immediate laugh that threatens. She will not laugh. This is not a laughing matter. Even if it's hilarious at the moment. She isn't even sure what's funnier, that Scar had partaken or that he'd called Henry and Heather 'Amestrian'. She knows what he means.

She also knows Envy and Heather very well. She knows full well neither of them would deliberately give Scar drugs without his knowledge. And certainly Henry meant no harm. It's easy enough to see what had happened. Henry had simply made tea for the household, and no one gave it a second thought. Scar hadn't known to ask and had drank a cup of tea. It was nothing but a simple misunderstanding.

That had led to - she assumes - a somewhat stoned Scar. Honestly she's rather sorry she missed it.

Now Envy's warning makes a bit more sense.

"I'm sure no one intended to 'drug' you." Said as much for everyone else's benefit as Scar's. "Are you alright?"
