Luke confronts Jaba, kills the Rancor, feeds henchmen to the Sarlacc in the Pit of Carkoon, Leia strangles Jabba, and they blow up Jabba's pleasure yacht.

*The Emperor arrives on the TDS. He still has plans to turn Luke. They know about the Rebel Fleet amassing in a nearby system.
*The rebels discover the location of the TDS, that the Emperor is overseeing its final construction, they believe it is not yet operable, and it is protected by an energy field originating on the Endore Forest moon.

*Luke tells Leia "the force is strong in my family, my father has it, I have it, and my sister has it", looking at her. Lightbulb!!

He tells her he must face Vader.
