Aria huffed out a breath as she sat up when the shuttle finally stopped rocking from side to side and levelled out. "Who taught you to fly, a bloody drunk?!" the way she clasped one palm against her forehead would prompt the conclusion that the clanging sound had indeed been her head connecting with the wall as they had exited the planet's atmosphere, even if she didn't confirm it directly. 

Shifting to a more comfortable sitting position, she met his gaze but remained silent until he spoke first, apparently having been exhausted of any other verbal jabs for the present moment. 
"Aria." she muttered, dropping her hand back down to her side and smirking wryly. "In case you missed it." her brow furrowed as she tried to recall when it was that Lysa had first appeared on Korriban. 
"Yes, I would say so." the acolyte answered slowly, counting off a few dates or months (she never vocalized exactly what it was she was counting) on her fingers, she nodded again when she was sure that the timeline worked out correctly. "Probably about a year or so ago, yeah." 

"I thought she was just another wannabe. Y'know, a Jedi washout that didn't get the glory she was hoping for out of the Order." another smirk played across Aria's features as she leaned back against the seat, trying to relax as best as she could being stuck in a shuttle with someone who was supposed to be her enemy. "We get a lot of those showing up, 'specially recently; most of 'em don't last a month. Turns out she was much better than that." 

She couldn't say for sure whether Lysa had had a genuine interest in joining the Empire's regime or whether she had indeed been a Jedi spy as the rumors seemed to indicate. Aria had never made much of an effort to talk to Lysa beyond the taunts the pair had exchanged in the duelling rings once or twice. 
"If she [i]was[/i] faking it the whole time, then she was pretty good with mind tricks and concealments, to hide her intentions from the Dark Council like that." it was the closest thing to a compliment directed at Yerbol's sister that would likely ever leave Aria's mouth. "If they had suspected even for a moment that she was intending to feed intel back to your Order they would have killed her long before they let her contact you...or maybe they were screwing with her the whole time, testing her to see what she would choose when you turned up." Aria shrugged in conclusion. "You probably don't want to even consider that your sister would stab you in the back like that, so hey if it makes you feel better to think she was still on your side, don't let me stop you."
