Jo'ren spotted the twi'lek as she was leaving, having only just met her a short time before. She was in a rush though and he had no interest in stopping her. As he walked through the halls he saw Shaisha and threw her a wave, but had business elsewhere. Eventually he arrived back at the work station where he had worked with Gerry and the holocron to craft his lightsaber.
He removed all of the pieces from his utility belt and set them out carefully. To inscribe changes into the gem would be a tricky process and he was no expert at this. So he was going to rely upon the force and good old-fashioned superior technology.
Removing the crystal he reached out to the force, and began to work on making it even deadlier than it already was... An hour or so of meditation and minute adjustments passed. He felt as though he was communing with his weapon, it was exhilarating!
And in the end it was spectacularly successful: Jo'ren's lightsaber crystal gains
