Obviously avoiding Caedus emerging was foremost on Mara's mind. She knew what it would mean if he did revert to that. And it would force a confrontation between them that Mara never wished to repeat. The memory of Kavan was still a potent one despite having been in Lawrence for over a year. Avoiding such a confrontation was Mara's primary goal, but likewise she knew Jacen's emotions were dangerous when unleashed. This was going to be a process that no doubt would be akin to brain surgery, proceeding with utmost care to every movement made lest one wrong move set bad things into motion.
Mara knew the opposite of Jacen's current cold demeanor meant Caedus, but she wasn't going for the polar opposite. But of course moderation was never something Jacen had mastered. No doubt that was part of the reason the Jedi never saw fit to promote him within the Jedi ranks. And it clearly was what helped him slip to the Dark Side. Being unable to balance his emotions was dangerous, but Mara was going to try to help him find some middle ground and to help keep him there. The fact that Jacen had such a cold Force presence to her meant that he wasn't really dealing with the emotional toll of having lost his wife and daughter.
She wasn't about to claim she knew what he was going through. Losing both so close together was not an experience Mara had. She'd lost her husband to the Seal yes, so in that she understood the loss of a loved one. Though she also understood that the Seal was the only way Jacen would ever see his wife and daughter again in life, much as the Seal was the only way Mara could ever see Luke or Ben again. In that common ground she hoped she could gain a little ground with Jacen.
When the door opened, she walked in, closing it behind her, the followed Jacen's voice to the room he was in. It was eerie to see this coldness as well as feel it. It was just not her nephew whatsoever. Was she glad he hadn't immediately gone to the Caedus extreme? Yes she was. Still, she wasn't exactly liking this whole situation. Though the comment about the outlet for his frustration and rage wasn't missed. She was certain she knew he was speaking of Tahiri. In her conversation with Tahiri, while there were no details beyond training and hunting, Mara was fairly certain there was far more to it than that.
"Of course, getting to the point is a far better way of doing things." Mara walked in and sat down in a chair and looked at her nephew. "Which brings us to the part where I will tell you I'm not about to sit here and tell you I know how you feel because what good will that do? What I will tell you is I know that like you, this world is the only chance either of us have for seeing those we love most again in life. And no doubt you may not understand why I am worried about you, but perhaps that statement may shed some light on that matter for you."
