Like any sensible girl in the 1970s and beyond, Cait Brennan grew up having night terrors about "Little House On The Prairie"'s own Nellie Oleson, the meanest mean girl in all of the meangirliverse. This Friday, July 7, we'll see if she's got what it takes as Cait squares off for a no holds barred con kickoff Q&A with the mighty Alison Arngrim, the actress who brought Nellie to life! It's the beginning of a very full weekend of events at O Comic Con at the Mid-America Center in Council Bluffs. Cait will be playing two concerts, hosting the unofficial kickoff session and leading a screenwriting panel/seminar on creating great characters for the big (and small) screen! So many great guests at O Comic Con this year and we're thrilled to be a part of it.
