Envious
Pride is disappointed at Envy's birth, at the way the little wormy thing screamed and cried when it realizes it is alive.
"Do not tease Envy," Father says, then turns to Envy. "You are my Envy. You are part of my army."
'Part', Envy hears, not 'My only army.'
"Hey, Ugly," Greed says, ticking a finger against Envy's ear. He whispers in Envy's hair, "The ugliest of us all."
Envy chooses a cute form.
"You can't attract attention like that," Lust says, wrinkling her nose and folding her arms. The motion makes her breasts jut. "What are you, anyway? Male or female?"
Envy's choice is to be neither. Envy simply is.
Gluttony and Sloth are both too stupid to have an opinion. Envy's thrilled with their lack of reactions. Wrath, on the other hand.
"When you come to see me, appear as a military officer. My adjutant."
You were human first, Envy wants to say, I never was. You are an abomination, with your wife.
Envy doesn't say it though, any more than Envy says the other things that want to spill out. Envy is strong, and dangerous, and far more useful than any of them. Envy will survive all of this, and sit at Father's side after the Promised Day.
Envy knows, and waits for that day.
