Moving the idea from the General SW thread about Empire.

You've got the scene where Anakin dreams of Padme dying in childbirth. Replace Padme with Leia making racist/specist statements. Anakin kills Padme because Leia will possibly be a future racist/specist.

And there's other movies you could pull Carrie Fisher dialog from. Shampoo was around that time and I think she's got some adult dialog which could be worth pulling from.

...and now I remember that you're only playing with TPM...

nevermind.
