This scene was written this way, verbatim, in our planning notes years before we got up to starting detailed work on Return of the Jedi. The allusion to Star Trek II: The Wrath of Khan was just too delicious pass up.
As it turned out, when we got to the sailbarge fight, we came up with a better idea, and ran with it in the actual comic. I, personally, was very sad to see this one fall by the wayside. But I'm pleased that it has new life and finally sees the light of day as the final non-canon bonus strip in this extended intermission after the original six films.
As previously announced, the next strip will be the opening strip of our treatment of Rogue One, appearing on Tuesday 1 August. See you then as we continue the Darths & Droids journey into an exciting new frontier!
