A very odd thing happens to Olivia Moore in the opening minutes of The CW's "iZombie."

To be general, she becomes a zombie.

To be specific, her hair goes shock-white, her skin grows pale, she goes all raccoon-eyed, she dumps her perfect fiancé, she takes a major detour in her medical career and she starts eating brains.

Leaving the different organ consumption aside, most of Liv's changes are external and they're mostly very noticeable. 

One of the funnier things in "iZombie" is that while family and friends aren't utterly oblivious to the transformation, they're certainly oddly blasé.

In "iZombie," Liv's best friend and roommate Peyton (Aly Michalka) is busy starting her law career and I guess that somewhat explains how she's able to live with a zombie for several months without beginning to put together the pieces in any way.

Last week, Aly Michalka stopped by the HitFix studio to try to give an explanation for Peyton's limited awareness. 

I also chatted with Michalka about what drew her to "iZombie" and the chance to leap from her law-curious character in "Hellcats" to a full-blown lawyer for her latest CW offering. 

Check out the full interview above.

"iZombie" premieres on Tuesday (March 17) night at 9 p.m. on The CW.
