When it was clear that Obi-Wan wasn't going to move back from the white area, Qui-Gon made up his mind. He gathered the Force to him and pushed as easily as he could, trying to make Obi-Wan back away. When Obi-Wan fought against him, he pushed harder. His apprentice seemed determined to discover what lay at the source of the light, even more so by Qui-Gon's attempts to dissuade him.
He soon became locked into a battle of wills with his student, entrenched deep inside his own mind.
One moment Obi-Wan felt himself being drawn toward the secrets he was certain lay beyond the white area in Qui-Gon's mind, the next he felt as if he was battling a wall.
The resistance increased until Obi-Wan finally backed down. Only at that moment, he felt a surge in the Force that was trying to push him away. Shock filled his senses when he was not only pushed from Qui-Gon's mind, but across their quarters as well.
A searing pain across his mind was the last thing he felt before everything turned to black.
Qui-Gon marshalled his strength, prepared for a final push to free Obi-Wan from his mind. He realized that his Padawan had loosened his grip a moment too late. He could only watch in horror as Obi-Wan was shredded from his mind, and propelled across the room.
Jumping up from his seat, Qui-Gon rushed over to Obi-Wan. He pulled his unresponsive Padawan into his arms. Their bond was strangely quiet, what he could make out over the burning that remained in his mind. Qui-Gon reached out and touched Obi-Wan's face with a shaking hand. His heart was pounding in his chest, and the fluttering breath that he could feel on his hand did little to calm it.
Although the area along their bond was still tender due to his forcing Obi-Wan from his mind, he reached out to his student. His concern only grew when not only was the bond silent, but he couldn't feel Obi-Wan along it at all. Wanting to berate himself for injuring his student, but willing to waste the time, Qui-Gon pressed gently inward searching for Obi-Wan.
He was shocked by the depth to which Obi-Wan had retreated into his mind, as well as the knowledge that it was his fault. He followed the faintest trace of their bond before feeling a far-away flicker from Obi-Wan.
Qui-Gon wasn't sure if he had sensed his student or not, and called out to him. /Obi-Wan?/
Obi-Wan doesn't reply.
