Really enjoyed this episode, it didn't make the most sense at times but made up for it with an extremely disturbing core concept. And there is comfort in the idea that even without a significant portion of our memories, we're still "us".

I'm confused about one thing though and maybe I just missed something so someone can enlighten me. If the palace is so well-protected that just literally being inside it for ten minutes is enough to completely reverse the memory loss, why was Pike first affected by it while standing in the palace? Is it just that they weren't in there for very long during their first encounter with Zac, and the symptoms caught up with him, or did I miss something about how that worked?
