Mara just smirks
"Sorry," she says, "but the Emperor needs my services elsewhere. No time for either choice. Oh, and by the way, one of the guards on that skiff was Lando Calrissian, a known associate of Solo's."
Jabba's anger rages. This mere woman was defying him, and revealing his palace had been further infiltrated.
"Execute her!" Jabba screams in Huttese, as Mara heads for the top hatch. A blaster shot rings out, hitting Mara square on the chest. She drops lifeless to the deck. Jabba laughs, then tells his guards, "Toss her body to the Sarlaac."
As Mara is carried away, Jabba's attention returns to Leia, who is still topless. His tongue licks his lips as his tail throbs with anticipation. He says something in Huttese, which Threepio reluctantly translates. "The aroused Jabba is ready to enjoy you in every possible way, and adds that now that Master Luke and the others are gone, you have nothing to negotiate with. I'm so sorry, Your Highness." Jabba drags Leia into a private chamber of the sail barge.
