its so un jedi like.. reporting on your colleagues
You must of not actually listed to any of the VO work for that quest then.
It was quite clear that those two were no where nearly ready for any kind of relationship, they were already starting to twist the jedi teachings and code to suit their desires. The girl was clearly already starting down the path of the Dark Side because of her emotions.
They were also padawans, and not full Jedi Knights, so they still had much to learn and prove.
It's amazing how many people play though that quest yet don't actually pay any attention to what is really going on, or why you're doing what you are doing.
BTW the Sith method of dealing with a situation like that would of been to kill both of them, and take the price she was offering.
