Hi - my husband and I just saw STID and I have an initial question - why did Kirk and Spock seem to not really know who Kahn was? I thought the Eugenics Wars still happened in this timeline (in some form or another). Wouldn't there be some information in the Enterprise computers if they input the name Kahn? Or did they just need a reason to bring in Nimoy for a cameo?
Neither Kirk nor Spock had any idea who Khan was in "Space Seed," either - it most of the first half of the episode for them to arrive at that tentatively and then try to draw him out in conversation.
