Camas — Few scream "Mommy!" better than Cameron Kolkemo. Kolkemo, who is 10, proved it to the world in an episode of "Grimm," the fantasy-horror show shot in Portland, which aired on Nov. 1. She's the older girl freaking out as a zombie attacks the family right at the start of the episode, which you can see at www.nbc.com/grimm/video/ptzd/n42591. Kolkemo has appeared in two other episodes of "Grimm" too, and in a few other local TV productions.
