Ever wondered why Cozy Glow is an evil filly? My sister brought it to my attention that she might only be wanting a home. I mean, we never see her parents in the series, so she's been alone.
Being alone with everypony staring at you is bound to drive somepony into madness.
But when Tirek comes by one day, her life starts to change in ways that shape how she is today.
Original songs/lyrics by me.
