Welcome back, Jess! :D Hopefully things will calm down for you a bit, huh?
Soooo the meme kind of horrified a part of my RPer's brain, I confess. But work commutes are boring things, so I ought to thank you for the distraction. ^_^
Divorce: Hopefully my fellow Rome fans will not beat me bloody for this, but I thought of an alternative for Mona. She is so Rhona Mitra in my head that it's not funny and I always figured that was it, end of conversation. Except the haughtiness, the ego, the absolute surety that she is the top of the top, a goddess first and foremost... Lyndsey Marshal. That would be under some duress, though. :/ And Desmond, well... He can only be Robert Downey Jr. The he couldn't be at first was one of the reasons I held off on him. There's just no way for him to work with anybody else.
Metatron: Yeeeah, I'm one of those people who can't change PBs, apparently. Clancy Brown is my end-all, be-all for The Voice. The only other person I could think of who might capture some of said voice would be Leonard Nimoy.
Carnival: Anthony Hopkins. I thought, for a moment, of Alan Cumming, but he's more cabaret than carnival. Carny talker rather than the god of the carnival.
Punk, Hephaestus, Envy and Steam Power don't get second choice avatars because there's no one else I could even conceive of as them. As it is, being able to come up with an alt for Mona broke my brain. >_>
