I found this while looking through my files. I wrote it at the end of Series 1, when I thought Raimundo had gone into the Mirror (as the title suggests). I'm going to carry on with this. Enjoy!

Raimundo's POV
"Serpents Tail!" I shouted. I was jerked off my feet and flew towards Wuya. I looked up. The other three had just arrived on Dojo.
'Too late, losers,' I thought to myself. I saw their expressions for a moment – Omi confused, Kimiko sad, Clay angry. I looked back to Wuya. I could swear she was smiling. Then I heard her laugh. I realised what was going to happen. I tried to stop, but I was too close. I couldn't release the Shen Gon Wu. At the last moment, I heard her say those two fatal words.
"Reversing Mirror!" There was a flash. I saw her morph into a human body. Then I was gone.

R&R, and bear in mind this is actually my first fic (in a way).
