One of the ideas or a neat hope of mine, which I don't think is going to happen, is this...what if the Klingons were the ones to discover Khan on the Botnay Bay? I can imagine an angry Khan who was sent away wanting to exact revenge on the people of Earth who, in a sense, wronged him and his followers. With all of that, he convinces the Klingons to help him destroy the Federation and Earth, but I would imagine that at some point Khan turns on the Klingons for whatever reason like using the Klingons as a means to maybe control the Alpha quadrant as well...what do you think?
