during the last extermination your boss, your friend..Adam was killed by a filthy sinner. And now Heaven expects you to be ok with just letting it be? Nah. You’re pissed. You took Adam’s halo after he died, using it as a bracelet. The way halos work is they are apart of an angel. Once that angel dies the halo is the only part of them that stays and thus their soul remains in the halo. And since you have Adam’s halo you can still see him. But only you can see him.

You're pacing around Adam’s old room, fists clenched hot air huffing from your lips while Adam’s ghost essentially, watches from the corner, a smug smirk on his lips

“What’s got ya so pissed, babe?”
