Use the (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 **** 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 ****.

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

Other Weequays: Not understandable language!

Weequay: Because this is the right thing to do! We have attempted ****, 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...
