I love to imagine that this photo, with its facial expressions that COULD be sincere, is actually ripped from a deleted Revenge scene in which these two are covering their hatred with smiles.

VICTORIA GRAYSON (left): Hello, husband-stealing slut.
LYDIA DAVIS: Hello, ice queen on whose ass you could freeze oil.
VG: Nice to see you classing up the joint for a change.
LD: You're so attractive for your age, Victoria. Why are you chopping your body into pieces? Can't you leave that to your enemies?
VG: Are you wearing red because it's the color of your venereal disease?
LD: My smile may appear friendly, but it conceals the soaring glee I feel at seeing you dressed up like you run a bordello.
VG: Why? Do you need a job? Husband-stealing isn't lucrative enough?
LD: It's more lucrative now that he's about to divorce you without giving you a single penny. Maybe. I'm a couple episodes behind.
VG: What?
LD: Um, never mind. Just know that if your fingers snap from my iron grip it's because I've been working out this hand for EXACTLY that purpose.
VG: And if your shoes seize up and slice off your feet at the ankle, it's because they hate you as much as I do.
LD: Kisses.
VG: Kisses.
