A continuation of Yang's feelings towards Blake, I keep seeing it as Yang will be angry at first, but that will fade and all that will be left is some level of hurt and disappointment. I mean, we all know she did this to protect Yang, but it doesn't change the fact that Blake just left. And even if Yang eventually forgives Blake, I'm pretty certain Blake is never going to truly forgive herself. Dammit RT, let these kids be happy!
Blake’s happiness and safety - her future - is entirely dependent on Adam. So long as he’s alive, she’ll never feel safe or believe that those she loves are safe. That’s why she ran from Yang, that’s why she’s still in Menagerie. The only real choice Blake ever made for herself was going to Beacon and it gave her so much love. But Adam took that from her and she won’t rest until he’s gone and she can finally breathe again.
So often people seem to forget Blake in all this and all she’s been through. She didn’t leave Yang because she didn’t care, she left because she cares so much.
