It was a long shot, but he knew that mutual meditation was a powerful technique that he had used on a few occasions with his Master to grasp principles that he had been struggling to grasp. Although it could be invasive, jarring and outright violating to have someone else inside the mind, it could also be a powerful means of transmitting concepts and truly knowing the inner workings of the meditation partner. If they could at least try to make sense of their bond now through meditation, Yerbol believed they could use it to their advantage in the troubles he knew they would face in the very near future. 

The thread that he followed to Aria's mind led him to a wide expanse of black nothingness that was occasionally punctuated by flashes of light above, then around him. Those flashes of light coagulated into actual memories, some of which were still frames of memories that Aria allowed him to see. Others were moving, fluid recollections that played in real time(well, however "real time" was perceived in this state). He felt her sharp jealousy when Lysa came to the academy, the ferocity of her desire to prove all those around her wrong, that she COULD make it not only as an academy student, but a full fledged Sith. There was anger, fury, determination, sorrow and a host of other strong emotions that were beginning to creep towards him as tendrils snaking from the memories towards his torso. The tendrils didn't actively pursue him, but instead hovered around him in a holding pattern as he moved forward. A few moments later, one of the memories cleared away to his right, Yerbol able to spot Aria in a similar location about fifty yards from his location, eyes wandering around flashes of memories in front of her. He wondered what she would think of the things she saw...the pain of seeing comrades falling under the heel of the Empire, the joy of spending his youth wandering around Tython with Lysa, the frustration of learning some of the more difficult tenets of the Order, the doubt he had in the Order that he repeatedly talked about to Master Paz, his only Master, a compassionate man that taught him discipline and mercy COULD bind together among other things. There were a few memories that he wanted to keep gated, mainly out of shame. Some traumas needed to be buried, especially from a friend who didn't need to see things he never wanted to relive again. 

Yerbol hadn't spoken to his meditation partner for quite some time, allowing them both to soak in the experience before they decided it was enough(which was never spoken, but understood...yet another consequence of the strengthening bond). When Aria asked about the implications of what they had just done, he responded as he stood up, helping her up:
"I think so...I mean, in the short time we've spent together, our bond has only gotten stronger. What we just did seemed to infuse what we already have with even more energy. Here's hoping we can translate what we just did to fighting the Sith off...kinda like we did when we killed that projection in the temple?" A playful smirk came to his face.
"You gotta admit, that was wicked awesome. I can't wait to see what we can do in the future." He sighed gently, placing a hand on her shoulder, unconsciously drawing slightly closer to her as he said in a quieter tone:
"All that stuff you went through doesn't matter now. You don't have to walk around with a chip on your shoulder...not around me at least." He looked away briefly, clearing his throat, the solemnity of his voice surprising even him as he continued, resuming eye contact: 
"We used to define ourselves by what we were as Jedi, as Sith, but now...now I'm choosing to look at Force users, at us, differently. From here on out, you're not a Sith trying to prove herself to some mysterious dark council and I'm not a Jedi attempting to bring some idealistic peace to the galaxy. We're two people trying to navigate a messed up galaxy and hopefully try to put it back together with a LOT of help...oh and the Force. That too." His hand dropped to her arm, shaking his head.
"Honestly, I don't know if I'm trying to motivate you or help you or..." He chuckled slightly. 
"I guess after what I saw in your mind, I just realized how awful it was that we were indoctrinated by those around us, that we couldn't choose how to define ourselves, our beliefs. We have that chance now. And I'm really happy that I'm doing this with you."
