Use the force (Mind trick)

Lana (using mind trick on the Weequay): You will tell me where she is!

Weequay: I will tell you where she is. We have taken her to the Western Dune Sea to rot to death there. It was the special request of the boss. She sure has tried to walk her way back, but she must be dead by now!

Lana (using mind trick on the Weequay): You are going to give yourselves up at the authorities for attempting murder.

Weequay: We are going to give ourselves up at the authorities for attempting murder.

Other Weequays: Not understandable language!

Weequay: Because this is the right thing to do! We have attempted murder, we must pay the price! Follow me lads!

Lana (thinking): Bastards... But at least there will be no further trouble with them anytime soon...

You leave the cantina, rent a speeder and set out to search for her, with hopes of finding her alive. In a few hours of searching your speeder's lifeform detector shows a living being not far from you.

Lana: It might be her! I must check it out!

You drive to the location the detector showed as quickly as possible. Rarely anybody survives a few days in the scorching desert without any water... Furthermore, it would be a miracle if she hasn't been attacked by Tuskens...
