The alien blobs want radiation from blowing up the Moon's nuclear piles.
REVIEW: There's nothing wrong with Part 2 of this story - after all, it's kind of doing Oculus, which was awesome - except perhaps the fact that there really was only enough story for maybe 1½ episodes. Consequently, Part 2 has extended action sequences that don't do much to advance the plot, and which seem to take place in slow motion, even when we're not on the lunar surface. That said, it's not a bad episode, but it isn't great. Merely fine. They might have spruced it up with more character development scenes, like showing us some kind of reaction from the Alphans to finding out they were tricked with memories of their own loved ones. That would certainly have been better than the forced laughter of the coda. I would also have liked to see more of Alan's hallucination, tying it more closely with his actual actions on the Moon. It's kind of a wink that New York is actually a waste dump, but they could have done more with the idea.
The plot doesn't hold many surprises. Koenig, finally acting rationally, convinces Maya and Helena his visions are real, and together they figure out a way to convert everyone's brains to truth-sight. The aliens hold on to the guys they need to blow up the nuclear piles, and a couple of fighting sequences ensue. We see a lot more of the mucus aliens, which isn't necessarily to the episode's advantage, but it's fine. That word keeps coming up. Fine. That's because it's all it is.
REWATCHABILITY: Medium - Serviceable conclusion to an above-average story; doesn't strive to achieve more than what is required of it.
