We don't know that this is official (I haven't seen this anywhere else, and IMDB isn't 100% accurate since it can be manipulated by various users - Bella's Stove, anybody?), but that is what it says on IMDB!
However, IMDB also lists Chaske Spencer as LAKOTA. Who the Hale is Lakota?
P.S. Is it nepotism or just a big ol' coinky-dink that Justine has the same last name as Patrick Wachsberger, Co-chairman and president of Summit?
Thanks, Mary G!
