I watched The Wrath of Khan the other night and was bothered by something. Khan captures Reliant with the help of its captain and first officer but asks Kirk to give him information about Genesis? Reliant was assigned to find a test-site for the experiment. Wouldn't they have more data about the project than any other ship? I know Khan wanted revenge on Kirk for what happened to him and his people, but his asking Kirk for the information makes no sense. The only reason Kirk had access was due to his position in the admiralty (as far as we know), but Khan had no way of knowing that beyond what Chekov or Terrell may have told him (and they wouldn't know for certain), as well his gamble that Kirk would have looked up the information after getting the garbled message from Marcus. So the question begs asking, why didn't Khan just take the information from Reliant's computer? I suppose it's possible Terrell or Chekov shook off the effects of the eels long enough to delete any pertinent files, but we've no way of knowing that for sure. It's only speculation.
