They continue to troll everyone. "the alliance seems to have let him out" and "Anduin now definitely is the one that did it"
BUT WE STILL NEVER SEE HIS RESPONSE. We don't get a clear "Oh yes Anduin I will turn on my former comrades!" but we're definitely moving in that direction. Anduin just...leaves that door open to him.
I think the major takeaways here are:
-Anduin did it. I am not surprised, but is he technically a traitor now too? Man I don't even know anymore.
-The Alliance is losing. They are trying Saurfang as an "ace in the hole"
-Saurfang is really torn up about all this. He clearly views the Horde as his family, one he is no longer welcome in. Sylvanas continues to push him out, but he doesn't want to join the Alliance. He just wants the Horde back to how it was when it was actually worth fighting for.
She kills all the ones who run for the alliance keep, and all the ones that run for her. The only survivors left the meet n' greet early because their old friends couldn't handle their stank. She also killed Calia for instigating it (though Parqual was who convinced her) but she got better-ish.
