Her own disc contains positive memories, but they're ones Leia's not yet ready to see. Whether it's simple intuition or the will of the Force warning her against overwhelming herself, she placed the disc in a drawer to be viewed another day. A day when she's ready to hear her mother's dying insistence that there was still good in her father, when she's ready to see herself taking part in the legacy he left her.

Jedi grace and reflexes save her from crashing into Elena and the wayward kitten, though she was apparently too distracted by her fury to notice the other girl's familiar presence drifting towards her.

Elena, she's never seen a kitten before. It was like a pittin, yet somehow far more adorable.
(Don't let Leia name it. She named her childhood pink pittin AT-AV: All-Terrain Attack Vehicle.)
