To be frank this episode was a bit of a letdown for me. It does explain why the Emperor wants to see Seras dead, why Civit is so bloodthirsty, why Touka didn't use Pigimaru right off the bat against Civit... but the manga chapters do all of those in a more exciting way, less as "passing comments" and more as part of the plot, you know?
Plus the scene where the Emperor was losing his shite thinking on Seras is way funnier.
Don't get me wrong, I'm still watching it, and I'm enjoying the series. But it could be better.
