ohsam | Plot bunny based on 6.13

Okay, so that last scene, with the first crack in the wall (MEEP!), got me thinking:
November 9, the night the Berlin Wall fell, would probably be a national holiday in Germany except for one not-so-minor detail: that's also the anniversary of Kristallnacht. There has *got* to be some kind of h/c fic for Sam using that fact as an analogy, whether it's a 6.13 tag with Dean admonishing Sam not to scratch or the Mauerfall proper. I can see loooots of angst potential, and maybe Dean saying something about it all being against the Geneva Convention; but should the wall fall, if Sam can come through it with his sanity intact enough to warrant the following joke at the end, or some variation thereon, I will be all the more pleased:
"Früher hatten wir 'ne Mauer,
Jetzt haben wir nur noch Beckenbauer."
("Earlier we had a wall, / Now all we've got is [Franz] Beckenbauer" -- it's from Die Prinzen's hilarious song Monarchie in Germany.)
