Evidently, based on what he said, McCoy had apparently helped open the torpedo the first time, probably not by himself; he wasn't a weapons expert. But the Enterprise obviously had other engineering personal, and a certain Carol Marcus who was a weapons specialist. She was on the Vengeance, though, and would've remained there when Khan intended to make his deal with Spock...
Maybe McCoy would be more forthcoming than Kirk had been.] You said your arm was trapped in one of the torpedoes. You must have found the time to tell Mr Spock how to open them safely, so you could remove the cryotubes before he handed them over to me. That was why, as Kirk told me earlier, they were still on this ship when I attacked. [He sounded even more sure of himself than he did when he told Kirk of his theory, taking only a small glance down at the torpedo as he spoke before he looked at McCoy again, hoping his guess would be verified this time.
