The most wanted villain in recent memory, having been captured by Starlight Glimmer, has been requested by Cadence to be put up for redemption.
The catch?
Chrysalis has to choose a husband from a list the Princess of Love has crafted after three days and two (mostly) sleepless nights of coffee fueled discussion. Energy drinks were consumed. Donuts suffered inglorious fates. Prince Blueblood was put in charge while the sisters delt with lending a hoof in deciding the fallen changeling queen's fate.
Her other choices?
Celestia wants her turned to stone.
Luna wants to send her to Tartarus.
Stone, Tartarus, or marriage. Those are her choices.
Cadence won't let her choose the first two.
