User blog comment:Mr. Ob(li)vious/Is Blake's character inconsistent?/@comment-3146930-20130920104553

The way I see it, Weiss doesn't have a problem with Blake at the moment because she is too busy being mad at Ruby. As far as personality, she seems quiet, but not completely anti-social. I think Maybe Yang helped open her up more and we don't know exactly how much time passed between the completion of the Emerald Forest and the start of classes. Maybe they had a few days of rest and getting everything set up; enough time for Yang to infect her with her cheer.
