Pellucidar!

I was going to say that!

misses the references and apparently the fabulous prizes

According to Google, it's a world at the center of the Earth, created by Edgar Rice Burroughs.

Also, I still say they're in the Savage Land.

I found that too, P-C. Thanks.

What's the name of that Classic Star Trek episode? "The Earth Is Hollow, And I Have Touched the Sky?" Something like that.

According to Google it's "For the World is Hollow and I Have Touched the Sky"

Anybody bring up the idea that maybe the entire island is fake? A giant, floating, island-looking secret mess-with-your-head lab?

I thought about it, but that's so far beyond current technology (that island is MILES wide, yo!) that they better explain it with aliens if they go that route.

Well, there was an alien in the Faster Friends story that they said was 'chosen deliberately'. If I was doing an epic explains-it-all fanfic, I'd probably go for some sort of amorphous alien in the island's matrix, with some sort of id-powers ala Forbidden Planet.

I don't know about the rest of you but I want to see a Vincent flashback episode. Yes, that's right, the dog. I'm not trying to be silly, really. Think of the possibilities. Being that he's a dog, nobody's going to censor themselves around him so even if he doesn't understand exactly what's going on the audience will. Through Vincent's eyes we can see the cast of characters with their guards down at various times on the island or even some strange phenomenon he's come across. For example, maybe he had an encounter with the island monster or maybe he witnessed Ethan doing something sinister well before taking Claire. The episode practically writes itself.
