Harmonies
Harmony - two pieces of music playing as one to work together to complement each other. One piece doing what it does best (eg - alto) the other what it is able to do best (eg - soprano), to make a fabulously crafted piece of music.
To many, in a crisis – wraith attacking, Atlantis' systems failing, John Sheppard and Rodney McKay seem to work in Harmony. One of them – Rodney – works out the best way to save or destroy something whereas the other, John, works out how to implement those plans. That's how a team should work. In harmony.
