We just don't say "doppleganger" enough. (Let's see how often I can get it in this post ;)
Twin, clone, brotha' from anotha' motha', double, identical strangers... all of those work too. But they lack the finesse and fantasy of...doppleganger.
Doctor Who recently encountered dopplegangers. (It might have been recently...time is kind slippery around the Doctor!) Anywho, they were fabricated from goo so that workers could deal with acid without risk to their own bodies...until....well, no spoilers. The point is the Doctor is the kind of person who knows how to use a good word.
A film called, Another Earth, talks about the possibility of dopplegangers who live on an identical Earth. The main characters have undeniably messed-up lives. As they dream about what their "other selves" could be doing out there on another world, they try to encourage each other to make the best of what they've got. Rhoda tells this story of a Russian cosmonaut turning an annoying sound into music.
The idea of roses from ashes isn't new, but I love how it's treated in this quiet simplistic science fiction. How can you recover from a really horrible mistake? How can you live after the complete devastation of all you hold dear? How many of us wish we had a doppleganger that could show us what our life would have been like, or one who could do our life differently for us?
One of my favorite songs is "Held" by Natalie Grant, where she sings of being held by her Savior Jesus. "How it feels, when the sacred is torn from your life
And you survive, This is what it is to be loved and to know, That the promise was that when everything fell
We'd be held."
Maybe we don't get to have doppleganger second chance, like in Another Earth. Maybe we have to make music out of it, like the Russian cosmonaut. Maybe we have to reach out to Someone greater than ourselves.
