I don't know, hasn't the internal twin thing cropped up in a bunch of shows recently? Though they did choose an interesting manifestation.
'A Hole in the World'
Natter 46: The FIGHTIN' 46
Off-topic discussion. Wanna talk about corsets, duct tape, or physics? This is the place. Detailed discussion of any current-season TV must be whitefonted.
Leif's too sweet.
I haven't seen chimerism on other mystery shows but surely many people saw I Am My Own Twin on Discovery Health. I thought it might be a solution from the ads, so I was surprised when it actually turned out to be the ultimate diagnosis.
ETA: I guess it was on CSI recently. (xpost with msbelle)
CSI, I think
In my defense, it was a MASSIVE crush. Formative even. His character wielded two swords, sheathed in scabbards on his back. And we went on to have a lovely chat.
ita met He-Man?!?!?
Skeletor?
CSI, I think
And the Venture Brothers! Sort of.
Also on Grey's Anatomy, IIRC.
Plus, they never explained how the titanium got in his neck !!! Very sloppy writing.
The medicine was sloppy, but I thought the dialogue was fantastic.
