Tonight's Fringe 2.6 considered one of them - actually, a possibility that the U.S. was concerned about, regarding our own astronauts. They were quarantined at first, to protect us from any exotic organisms they might have brought back home from space.
This was the the different "stripe" of incredible, as Walter put it, that Fringe explored tonight. As Walter also said, those "pinkos" were up to all sorts of bizarre activities. One of which was their treatment of a cosmonaut who returned from space with an alien, shadow passenger.
Not the most original theme in the world - or, in places beyond our world - but, as I've noted about Fringe frequently, it excels in the retelling of classic science fiction motifs. Tonight's retelling embroiled Broyles, and gave us a bit of back story on how he lost his family - his wife left him, and took along their children - as his attempt to keep them and the world at little safer kept him too far from home.
But the best parts, as often on Fringe, were the visuals. Tonight's alien turns people into dust, leaving their skin intact as a fragile shell, which a strong breeze or the gentlest touch can shatter. The most memorable scene was a fly landing on a face, and causing it to crumble.
Fringe itself sometimes seems to be a such face. I hope we keep seeing it on television.
