Spoiler - Ausiello

Question: Anything — anything — you can tell me about Castle‘s zombie episode, titled “Undead Again”? —Cat

Ausiello: It airs April 30, one week before the season finale — and that was by design. “As part of this final Beckett/Castle run-up to a very emotional finale — where we confront a lot of the issues that the characters have been skirting all season — we felt like it was important to bring some fun into the show,” series creator Andrew W. Marlowe told TVLine’s Matt Mitovich. “Zombies are very much in the zeitgeist, and we thought it was something that was worth tackling.” The boss man hints that he found a “credible” way to incorporate Walkers into the procedural à la how “last season Castle was convinced that aliens were behind a murder.”

Question: I’ve thought long and hard about this. Would the mystery person you said is returning to Castle during May sweeps be Kate’s father? We haven’t seen him since the premiere. —Bexx

Ausiello: Nope. The character I was referring to in last week’s Ask Ausiello is female. And she has ties to a former series regular.
