The key to this episode is remembering: In Mobius, people are who they wanted to be in real life. There are some pretty surprising twists and some very emotional revelations. The episode oscillates between Ritsu's inner conflict and the battle between the Club and the crazy girl who blows everything up. One person fights with their own being, the others with a dangerous enemy. Both storylines are very interesting to follow, and the episode becomes quite engaging. There are some logical questions about how the app makes people sleep forever, but hopefully, they'll explain that later on.
