Nigel was last seen in the episode where Clark was going to take Lois to breakfast at Callard's and tell her he was Superman. The one where Superman froze her... And the Answer Is (?) I think that's the name of it. I do know that's the ep. At the end, the bad guy (I forget his name-- Mazik! Just remembered! smile ) poisoned Nigel.

And his last name was St. John.
