User blog comment:Mr. Ob(li)vious/Is Blake's character inconsistent?/@comment-17774063-20130927010354

My impression of Blake is that she's a very laid back go with the flow character. So in my mind I don't find it strange. Plus it's obvious she made friends with Yang and it could be that Blake had that personality in her all along and Yang just brought it out.

My second theory is much darker though. The black trailer left me with a betrayal vibe from Blake and I can't help but feel that she's putting up an act because she's trying to get revenge against Weiss' family somehow.
