iZombie shook things up in its third season by revealing the undead to the world — and the surprises have only just begun.

The cast and executive producers of the CW series — Rose McIver, Malcolm Goodwin, Robert Buckley, Rahul Kohli, David Anders, Aly Michalka, Rob Thomas and Dianne Ruggiero-Wright — assembled for the show's San Diego Comic-Con panel on Friday to tease what's next for Liv & Co:

* "Season 3 was a dream," Thomas joked atop the panel, explaining that revealing zombies to the world was always part of the show's long-term plan. "Admittedly, we ... might have gotten there a little sooner than we thought."

* As for how Liv feels about the crisis in "New Seattle," McIver said, "At least she has this community of people around her who know and support her. ... It's going to be interesting what side of the fence she falls on. Her position on the whole thing will find a new identity for her throughout the season."

* "I love playing the human dynamic," Kohli said. "It's what the audience can connect with." He did, however, admit that it's "tempting" to want to play a zombie.

* "He's going to be there for [Dale] just like he's been there for Liv," Goodwin said of Clive in Season 4.

* And is Major firmly #TeamZombie? "He's had a pretty rocky road," Buckley acknowledged. "He's kind of found a home in Fillmore Graves. It provides him with a sense of purpose, which he hasn't had. It also gets his mind off the whole 'girlfriend exploded' thing."

* "It's fun to have Blaine back to his old mustache-twirling ways," Anders said, cueing up the big reveal: Robert Knepper (aka Blaine's father) will be a series regular in Season 4.

* "Angus is going to get out of the well, and he's going to be up to no good, and he's going to have some very hardcore pro-zombie people on his side," Thomas revealed. "There's going to be a human terrorist organization that doesn't want any human-zombie fraternization. This is not about one big bad this year. It's coming at our characters from all sides of the spectrum."

* Thomas also teased lots of "friction" between Major and Liv — and not the good kind.

* Lastly, "There will be a gentleman that Liv will take a fancy to, named simply because of the 'shipper name that will stem from it," Thomas teased.
