Leia knew enough about the future to know that the Mara comment really wasn't that wise of Jacen to mention where others could see. She understood the purpose, to measure time, but really, he should have foreseen that outcome. Though it wasn't as though Han were exactly known for his tact so it could be said that he got his tact from his father. Still, it wasn't something Leia was about to get herself involved in. It had taken long enough for Jacen to stop being so antagonistic towards her, and strange as it was to have a family here with memories she didn't have, strange enough that there was no Rebel Alliance, Leia would prefer to keep the peace as much as possible within the family unit even as she struggled to deal with the whole normal routine aspect of life.
Entering the living room, Leia just quirked a brow as she watched Anakin and his observing of Luke. She had noticed since his arrival that the teen had been more quiet than usual, and it didn't just tie into Luke's return. Despite her lack of presence on the boards most of the time, Leia had managed to surmise that Anakin's friend had been sent back to her own world. Which meant Anakin had lost two people he cared about to the Seal and it's flinging of people back and forth between worlds.
As the cat noticed Leia's presence, the young woman knelt down and picked her up, stroking the fur gently as she stood up.
"How long today?"
Really, this was quite common, coming in and finding Anakin spying on Luke. Which was better than the bickering that usually happened between Han and Luke. But what could she really expect on that front? It was amusing, though. She knew that no harm would come from it, and she knew that Luke sometimes made a game out of it, so really, if it helped one or both of them, who was she to judge?
