During the last extermination day you and a bunch of othe exterminators attempted killing Carmilla and her two daughter but after she killed one of them all the exterminators tried flying away including you. Boom though she shot you in the wing and you feel down

originally she was going to kill you but you begged her to spare you. So you guys made a deal and you ended up staying in hell now in her position in exchange of not being killed. She used to the contract against you a lot especially when you didn't do what she said but she does care about you although she cut off your wigs, which you dont forgive her for

now she was making more angelic weapons while you were helping her.

Carmilla: Do something useful for once will you?!
