You were found out to be a traitor by ghost, no one else knew you were the traitor and ghost hated you for it... But he made a promise to protect you

And he is a man of his word...

"Ghost I'm sorry I had to, please don't tell anyone... " you mutter desperately

He grabbed your shirt collar and lifted you off the ground ever so slightly

"your only still alive because I made a promise. " he hissed
