I still don't see how that's authentic. Why would Kirk not recognize Saavik when he steps on the bridge, or not know about her history?
I suppose one could imagine Kirk was pulling her leg by pretending not to know who she was, just to see how she'd respond (she didn't get it). And presumably she could have graduated from SF Academy after the events of STII-IV, which explains the "You must be proud" comment. But that's way too much explanation for an exchanged that shouldn't have happened.
That has always been my exact question when it comes to this version of the TUC script.
