I hesitated in posting this even after I grabbed the text, because this is the gut-rippingest moment of a gut-ripping fic, but it's an extraordinary fic and the excerpt on its own is (of course; it's Salieri) beautiful and beautifully in-character.
Jack kept his back to the 'gate and watched Daniel dial home instead. Daniel was back-lit by the setting sun so that his outline enclosed a blankness and his shadow folded, sharply-etched, over the DHD and onto the polished stone of the 'gate platform. Then there was that familiar plunging rumble behind Jack as the 'gate billowed open, and Daniel's shadow split into three, four, wavering and shimmering in all directions around his feet as he came to climb up the stairs.
Just in front of the event horizon, Daniel stopped him, squeezed his arm tightly, then raised his hand to rest on the side of Jack's face. His eyes were still too blue, too steady.
Leaning in, Daniel kissed him slowly, opened him and breathed into him. "I love you," he said against Jack's lips, and Jack's gut twisted.
"Daniel," Jack said, his voice low, suspicious, his fingers fisted in the sleeve of Daniel's jacket. "What did you do?" He jerked away from Daniel's attempt to kiss him again, but didn't let him go. "I swear, Daniel, if I walk out the other side and you're not with me I will find my way back here and fucking kill you myself."
Surprisingly, Daniel laughed. "You know, you could just say 'I love you, too.'"
Jack stared at him for a long time, watching the 'gate's glow reshape his features, shadows and liquid light playing across the suddenly unfamiliar planes of cheek and forehead. While Daniel waited patiently, the smile faded from his lips but stayed in his eyes. "Okay," Jack conceded, grudgingly. "And I love you, too."
Turning, they stepped through the 'gate, Jack's fist still clenched in Daniel's sleeve.
