Aria smirked as Yerbol tried to dismiss her theory of Revan, and the cult following he had assembled when the Knight went rogue a second time, being somehow involved in this whole endeavour to re-shape the respective cultures that Force users grouped themselves into; then trailed off mid-protest as he seemed to realise that there was no substance to it and that the theory was entirely plausible. 
"In favour of what other title, 'just Aria'?" she quipped back at him, eyebrows raised as she stifled a laugh of her own, "Doesn't sound quite so intimidating, dunno if I could agree to that." The Knight didn't answer her, prompting a frown.

"Yerbol?" she called his name, concern creeping into his voice when his eyes remained closed and he still didn't respond. "YERBOL?!" she tried again, louder, fumbling blindly with the control panel in front of them as the comms started screaming loudly to announce an incoming transmission. Somehow, the shrill blaring of the comm unit managed to cut through the stupor induced by the vision, or whatever the hell it was he was experiencing.
"Hey, wait a minute-!!" Aria began to protest, but before she could so much as get the question out, Master Satele's hologram had vanished with no further explanation of why exactly they were banishing the Knight to his quarters, for how long the restriction would last, or indeed where she was expected to go, or wait, in the meantime.

The pain was so sudden and so intense that even Aria wasn't prepared for the sensation, it was like being sucker-punched in the gut and hit over the head at the same time...and that was just what she could feel through their link. She couldn't imagine the kind of pain Yerbol must have been in. 
Kill the Force...Aria wasn't sure if that was even possible, but she didn't like the idea of it, not one bit.
She nodded shakily in response to Yerbol's question, pressing the heels of her hands into her eyelids for a brief moment, she took in a shaky breath and finally managed to force her jaw to move and form words again. "Y-Yeah, what-what WAS that?" she swallowed the lump in her throat, looking across at the Jedi Knight. "Are you alright? I thought you'd passed out for a second there...man, I got a BAD feeling about this."

What had spooked Yerbol's Masters so much that they weren't willing to share with the duo? Did they know what had happened on the planet somehow, including the Force link that now existed between herself and Yerbol?
