I feel certain that one of you has this information readily available.

What, exactly, is the canon about John Sheppard's black mark? I know that the existence of a black mark on his record is referred to in the pilot, and the fact that he earned it by disobeying orders in a rescue attempt. Do we know who, if anyone, he succeeded in saving? Or how long ago this had happened? Pointers to the actual dialogue on which this stuff is based are extra-super-appreciated.

...Oh God I've just realized I have more than one thing I want to write for which I need this information. Did I somehow just pimp myself into SGA in 2011? IDEK.
