I heard once that they weren't in S4's "I've got you under my Skin". But if you go to CloisWorld's guide to L&C Characters per episode you should be able to verify. It's a pretty complete list.

EDIT: Hmmmm. That list says they were in that episode. The guide says that they weren't in every episode. Technically, they weren't in Soul Mates, but their souls were. wink
