I've always loved Kevin. He's pale, has long hair and a sallow face. Who wouldn't like him as a villain? His appearance in this episode does spice things up as he serves to remind Ben of his wrongdoing in the episode Kevin 11. Using his mysterious power to turn into all the Omnitrix aliens except Cannon Bolt, he manages to commit crime, get away from the scene before he is caught or suspected, and frame Ben at the same time. Now I call that remarkable.
I also like the particular scene when the SCAT agents discover Ben hiding among the crates and crying out like a scared little boy whether the monster had gone. It was a funny and witty trick and I respect Thomas Pugsley for writing this in. I've always had quite a low opinion of his episodes, you see.
Well-written is the only phrase I have for this episode.
