Does anyone know how to unock Juhani's side quest. The one that I am referring to is when that Mandalorian offers to buy her and then threatens to attack you. I have got him to threaten me but how can I get him to follow up with the attack. I have gone tantoonie, kashyacc and koriban and he has not shown back up. Please Help so I can complete this.

Talk to her often. Every time you level up. Every time you enter the Hawk. Etc.
She'll eventually tell you about her mother and father on Taris.
Then make sure she's in your party when you are entering(or leaving) a spaceport and the guy will approach you.

He approached me as I entered the docking ring at manaan. I spent a couple hours playing around there, then headed back to the Ebon Hawk. He was waiting there for me.
