Give her the robe, for a fair compensation

Lana (thinking): Alright, I have had enough fun with her, I shouldn't make her do the whole journey naked... Let's go back for her and give her this robe. For a reasonable price of course!

Upon returning to her she is glad you found something for her to wear! You explain her that even if you are a Jedi, you have to remain low on cash as a made up Jedi rule and she believes you. She offers to pay 100 credits for the robe once back on Coruscant and she has the means. You take her back first to Mos Eisley, than back to Coruscant with your ship. While flying back, she approaches you and tells you what a great misery it would have been, had you not bought her that robe! She would have been forced to do this entire journey naked!

You take her to the senate building where she can find her colleagues and receive further assistance. You receive the 100 credits from her assistant as promised. She was immensely grateful for your help and promised to return the favour one day. With your mission complete, you report back to the Jedi council.
