Red Dwarf - Here No Evil (Cured Redux)
The crew stumble on a science center where vile historical figures have been "cured" of evil.
I rewrote the episode to include my original character, as she's now a part of the crew. I didn't deviate too far from the script, but did add a sub-plot.
Of course, rewrites aren't for everyone - you're not obligated to read it. It's just something I've been wanting to do.
