Go.
He did as he was told, not yet at peace with himself, unable to gain the reassurance he sought. He could not bear to consider too closely what he had done. He did not want to ponder the result because he was afraid he might recognize something he had not considered and did not want to face. He went back to the warmth and comfort of the fire, seating himself next to Grianne, taking her hands in his and holding them while he stared into the flames. He did not look back at the shape-shifters, did not try to see where they went or what they did. He would not have been able to do so anyway, because his eyes could not penetrate the darkness beyond the firelight.
He stared instead at Grianne and tried to make himself believe that she had been worth everything that had happened—that saving her was not a Druid’s whim or a brother’s false hope, but a necessary act that would result in something more important and far-reaching than the losses it had caused.
After a time, he fell asleep. His dreams were vivid and charged with emotion, and they ranged across the length and breadth of his life. In them, Quentin reappeared to him, working on an ash bow, red hair hanging loose and easy, strong face cocky and smiling, laughter bright with reassurance. Coran and Liria looked in on him as he slept, and he could hear them speak of him with ambition and pride. The company of the Jerle Shannara filed past him one by one as he stood at the edge of a forest, and then Rue Meridian stepped away long enough to come over to him and touch his face with cool fingers that swept away thoughts of everything but her.
Finally, Walker stood looking down at him from a castle rampart, from a place that looked vaguely familiar. Truls Rohk stood next to him, then faded into a disembodied voice that whispered to him to be strong, to be steadfast, to remember always how alike they were. He was different than Bek remembered him, and after a moment Bek knew that it was because Truls was no longer a halfling, but a true shape-shifter. He was one with his new family, with his community, with the world that had given him a second chance at life. There was a sense of completion about him, of having found a peace that he had never known before.
Bek watched and listened to a box of empty space, to a wall of darkness, hanging on the other’s words as if to a lifeline, and the peace that Truls had found settled over him, as well.
When he came awake again, it was morning. A misty gray light rose out of the mountain peaks, east where the dawn was breaking. The fire had gone out, the smoking embers turned to dying ashes and charred stumps. He reached out his hand. The ashes were still warm. Beside him, Grianne slept, stretched out upon the ground, her eyes closed and her breathing slow and even.
He stared down at her a moment, then rose and went to find Truls Rohk.
He stopped at the edge of the flat where he had left his friend the night before. All that remained was a hooded cloak and a scattering of half-formed bones. Bek knelt and reached down to touch them, lifting the folds of the cloak away, half expecting to find something more. Truls Rohk had seemed so indestructible that it was impossible that this was all that was left of him. Yet there was nothing more. Not even bloodstains were visible on the hard, frost-covered ground.
Bek rose and stood looking at the bones and cloak a moment longer. Perhaps most of what Truls Rohk had been, what mattered and had value, had gone on to become a part of what he was now.
He wondered if the shape-shifters, Truls among them, were watching him. He wondered if he would ever know if he had done the right thing.
He walked back to the campfire, woke Grianne, took her hands in his, and brought her to her feet. She came willingly, her calm, blank expression empty of emotion, her limp acquiescence sad and childlike. He was all she had left, all that stood between her and random fate. He had become for her the protector he had promised he would be.
