The Warriors learn that Nohyas has been using a Selective Memory Magisword to erase select interactions with Prohyas's bizarre doppelganger.
- Art Shift: As below in Shout-Out, but Nohyas also makes up memories of the cast being eight-bit, and puppets.
- Call-Back: Nohyas recalls meeting the Warriors in several past episodes, even the ones in which he did not appear.
- Forgotten First Meeting: Several times, as Nohyas uses the Selective Memory Magisword to invoke this trope. It also explains why the Warriors don't remember being stuck in a cave with Prug in "Working Grup".
- Shout-Out: One of the memories is a parody of the opening to He-Man and the Masters of the Universe (1983), complete with Art Shift.
- Wham Episode: It turns out that Nohyas had interacted with the Warriors multiple times in the past and had erased their, along with some others', memories of him for little to no reason.
