The reason I referred to it as a plot twist is that Miles and Kerry have a very odd definition of what that phrase means, compared to most other people. As a story development, "Raven's Yang's mother!" isn't a million miles away from the "Blake's a kitty!" and "Penny's a something!" reveals we have seen so far, which were moments that were treated with so much heart-stopping, self-indulgent awe within the context of the show that you could almost be led to believe that the writers genuinely thought they had crafted a spellbinding work of art.

Maybe you're right and I'm just being an idiot, but I think we will be at least supposed to be surprised if/when Raven pulls a Darth Vader on Yang.
