There's a line in TWOK that I've never understood (not even to create my own misinterpretation). Now that the topic is out there, here's my request for clarification.
It takes place during the dialogue between Kirk and Carol Marcus in the Genesis Cave, after David, Saavik and Chekov have left the original chamber they'd beamed into.
At one point in the conversation, Kirk says something that "sounds like" ... "you say he's my son I'd be happy to help".
I've never quite understood the line; Shatner speaks it so quickly and kind of mumbly.
I believe the line you're looking for is ``you show me a son that'd be happy to help'' (Khan, in the task of killing Kirk).
