Part 3 of the Hannibal Tarot: Alana Bloom as Temperance. Temperance is all about balance and restraint, and Alana is always the one arguing for restraint. She’s the one always pushing against the extreme tendencies of her cohorts; she tries to stop Jack from pushing Will too far and tries, and Will clearly sees her as a sense of stability. In a show about cannibalism, I cast the most morally upright (IMHO) and ignored person as Temperance.
The peacock feathers are there to represent the wings on the Temperance card and because in episode 2 Alana mentions trying to raise peacocks like Flannery O’Connor, but giving up because their vicious birds.
