This was actually one of the episodes I've enjoyed most out of the whole season! Possibly because my expectations were low ... I went on my f'list while waiting for it to download and saw a lot of anti-squee (didn't read it, but it was obvious from the cut tags), so with that plus knowing it was a Mallozzi ep, I went in with basically zero expectations. And I loved it! The whole thing was all character stuff! Mallozzi does like writing the character stuff, which gives me hope for the movie. I saw all the plot twists coming a mile away, but they weren't stupid plot twists for a change; predictable, but it was actually kind of a cool idea, and they used the show's lack of logic against us! Things like Kolya appearing on the mainland with his nonsensical explanation for how he got there was a clue rather than a plot hole! It was actually a pretty awesome episode -- John's insecurities are EVEN MORE total canon now (man, I need to write up something about how John sees himself, because whenever he's in control of a hallucination, he spends the whole time FAILING and getting beaten up), and the episode dealt with Woolsey's insecurities and loneliness as well. And we got TEAM TIME! Remember season two? How we would have killed for FIVE SECONDS of the team eating breakfast together? And we got it twice, plus John and Rodney wandering off chatting with each other at the end, and all the solo character stuff in between.

I'm 99% sure that's what Rodney was referring to when he was talking about "mass hallucinations".

I think he meant the "Phantoms" planet, actually.
