Isn't PIS cancelled as well? Or was that the point.
Pretty much. A show doesn't have to exist to be summarized. In fact, not having it exist is sort of freeing. I've been merrily summarizing PIS since it went off the air and in my skewed opinion, the show's been a lot easier to deal with. Of course, no one's been reading those summaries, but that's what you get when you deal with the lost: a built-in silent audience.
So go ahead and write a summary for the eighth episode of FE anyway. It's not as if anyone's going to be able to contradict your statements for a few months, right? And with no readers to deal with, you won't have to worry about making any mistakes. ;>
