Here's an interesting idea: What if, in this universe, Ricardo Montalban wasn't REALLY Khan, but a bodyguard who took over the role to protect the REAL Khan? Our John Harriman could be the Real Deal. It makes sense too: Instead of the initial Botany Bay, another DY-100 Class ship took off as well, and without notice. The REAL Khan was supposed to meet with Montalban Khan, and when the 2 ships came within each other, they would of traveled together in a small convoy, only instead of THAT happening, the usual"Computer Malfunction" split the 2 ships apart, and the Botany Bay that we are familiar with is still drifting in deep space! The OTHER DY-100 drifts into Klingon territory, where the Klingons send the REAL Khan back to Qo'NoS and unfreeze him. Anyways, just an idea.
ALL PRAISE TO ZARDOZ!
GREAT SCOTT!!! ANOTHER FRIEND OF ZARDOZ!
