My theory about this:

So basically, a lot of people think of flash backs that are going to happen in episode 79 where we rewatch episode 60 with captions (or something more creative) but that is a widespread wrong answer…

The right answer is that the end of episode 79 unlocks something, that something is ANOTHER 20 EPISODE COMPILATION WITH SUBTITLES!!!

(The compilation will contain episode 59-79)
