I was thinking the flower smell was from a flower shop using a certain god for a mascot but I guess Hades makes sense. It seems we speak a lot clearer than he would've though.
I just figured that if this (if my theory is correct)Hades is one extremely pissed off and two only gave a short order. Also it has been a couple of centuries since the events when we saw Hades last so he could have changed since Asterion was punished.
