The CW’s iZombie had plenty of Veronica Mars baked into its brains already, between creator Rob Thomas and a host of past Mars favorites, but now Neptune’s greatest P.I. will finally enter Liv’s world. Well, mostly. What 50 Shades shenanigans bring Kristen Bell to Seattle for iZombie’s Veronica Mars reunion?

Per Entertainment Weekly, the season’s eleventh episode will see Bell putting in a cameo of sorts to Mars creator Rob Thomas’ new series, albeit perhaps only in voiceover. January 26 outing “50 Shades of Grey Matter” will see Liv consuming the brain of a poisoned young librarian, who herself wrote erotic fiction.

iZombie is otherwise keeping details of the appearance under wraps for now, but considering Bell narrated Veronica Mars in voiceover, much as Rose McIver does for the comic-adapted CW drama, it isn’t a stretch to imagine Bell’s appearance limited to a vocal one … for now. Bell will follow such other Mars alum as Ryan Hansen, Percy Daggs III, David Starzyk, Adam Rose and Daran Norris.

In the meantime, iZombie will return on January 12 with “Method Head.” They like wordplay, if you hadn’t guessed.
