Up the irons!!
Oh, well, apart from being a (very excellent) track on the (most excellent)
'86 Iron Maiden Album Somewhere in Time, (WHAT? hmm...another "coincidence" perhaps? Check out the track titles on that record!)....
Stranger in a Strange Land was also a (most excellent) novel written by the (also most excellent) Robert A. Heinlein.
So, what? Well, bear with me here.
Now, I'll admit that yes, I did read "Stranger", but it was about the same time as I bought that album, soon after its release.... So I'll also admit to forgetting nearly 99% of it.
Thank you Wikipedia for the instant memory! (And thank you high school for the forgetting part!)
"Stranger" is the story of Valentine Michael Smith and his "Tarzan-brought-home"-style integration back into Earth society. See, Valentine has been raised by Martians (on Mars no less) and is completely oblivious to "Earthian" culture. He got there because of a manned mission to Mars which never returned (Dharma anyone?) and was only found after a second mission.
Of course part of Smith's unique nature is his psychic powers, along with a "childlike naivete" (thanks wiki!) His starting of a philosophy of gaining complete understanding of everything (aka 'grokking')... Now, I'm wondering....
...Given that this episode is supposed to revolve at least in part around the children, current and possibly past who may have spent their entire lives on this island (*cough* Ben, Alex and the rest), and that they're only now being exposed to a different "culture" (the castaways).... Are we trying to draw a not-so-subtle parallel here? Especially considering Valentine's psychic and other strange abilities.
Or, alternately this (from the wiki article)
In short, he is a man besieged on all sides by those who wish to use him to further their own ends.
Like our hero, Jack? Juliet needs him to kill Jack, Ben needs him to save his life...argh. Will the madness never end?!
Or maybe its just a cool title that C&D felt like ripping off. Or they dig Maiden that much! (Eddie Lives!)
Just some amateur ramblings to consider. Feel free to object hysterically. I think maybe I do already!
