Points: 1. When Yang Xiao Long gets angry her eyes turn red. 2. Raven's eyes are sometimes red (most likely when she is angry). 3. Raven wheres a Grimm mask. 4. Grimm eyes are red.

Theory: In some way shape or form Yang Xiao Long has Grimm blood or ancestry, thus her Semblance is not a Semblance but a trait of her heritage.

i know this is an off the wall theory but i wanted to post it somewhere
