That’s probably one of my favorite episodes of the series as a viewing experience, it was pretty entertaining. I don’t think I quite track…the message, though? In the span of about three minutes we get explicitly told that for Pike and Ortegas the memory loss could be revealing experience that identified the core of the self, while for their friend on the planet it was an obscuring experience that robbed him of things he didn’t know were important. You can explain away the difference with plot logic pretty easily, but thematically it’s a bit weird to juxtapose them right next to each other
I think it makes sense that a brief bout of amnesia like that could be revealing of your underlying traits and feelings, but that in the normal course of things it’s very important to have your memories.
