To get the exterminations to stop, Charlie has to do some things that she really doesn't want to do. She's already tried talking to Adam, she already tried convincing heaven that redemption is possible. Nothing has worked. It's time to switch gears. If they won't accept her hotel as a decent replacement for the exterminations, perhaps Sera will accept a third alternative. (Repost from my AO3 account)

Y/n was a renowned angel in heaven. She was respected by all and was even well acquainted with the Seraphims, Sera and Emily. As a high power, her job was to take part in the Angelic trials, where she'd unravel many webs full of lies and deceit, then return home to Adam, her beloved. But Y/n had been caught up in her own web, visiting Lucifer in hell. She hadn't meant for the truth to be discovered, not like she had done any wrong. But she was tainted, and so she was banished from the heavenly realm, wrapped tightly in a silk of guilt and lies, and betrayal from the one she loved most. Centuries passed, and now she roams hell, helping Charlie Morningstar on her path to redeeming sinners. Unbeknownst to her, she's back on a certain path, face to face with her past, one that includes Adam.
