What ever happened to Mitzelplix?

What was that again? Season 4 or 5? I cant remember havn't been through my Smallville DvDs in a while, Still watching the show tho. Anyway what ever happened to Mr. Mitzelplix. Towards the end Lex was talking to him and wanting to use him for something but nothing ever came of it. They need to bring him back.

Didn't he get killed?

No, it was season 4, ep 7 cause that was when Clark was playing football. And yeah, presumably he gets placed in 33.1 .... thats how it ends anyway.
