catherine ohara bryan cranston 30 rock gi '30 Rock': Bryan Cranston and Catherine O'Hara fill in Kenneth's family treeWe’ve been to Kenneth Parcell’s hometown on “30 Rock,” but we’ve never met other members of his family (aside from cousin Clay Aiken).

That will change in the show’s final season. Catherine O’Hara (“Best in Show,” “Temple Grandin”) will guest-star on the series as Kenneth’s (Jack McBrayer) mother, and “Breaking Bad” star Bryan Cranston will play her “friend” Ron, TV Guide reports.

Kenneth and Hazel (Kristen Schaal) will be involved in a “non-sexual” relationship at the start of the season, “30 Rock” creator/star Tina Fey tells the magazine. She doesn’t spill any details about how mom and Ron come into the story, but perhaps Kenneth thinks it’s time for Hazel to meet the family?

We do know this: Kenneth loves his mother even more than he loves everyone else, and Ron was not kind to him after Kenneth’s father died. Which should make for some interesting dynamics when we finally meet them.

“30 Rock” begins its final season on Oct. 4. Check Zap2it’s premiere calendar for all the fall debuts.
