It probably is just this episode. They did the same thing although just at the start instead a whole episode with the Comedy Central Channel bit in Rebirth.
Overall it wasn't the strongest but had some great jokes. I'm super excited for the rest of the season and I'm glad they are releasing weekly. I keep visiting the page to see when the next episode is released and end up watching more old episodes.
I think the first book would make a great mini series. An opening, an episode for each character and 2 episode finale of the story. Endymion would make an awesome movie though
