Bendreas + them dancing at the party before going on Burned Ones' hunting after which Andreas does never return
Ok so it doesn't quite fit the prompt but I couldn't leave it at a sad ending:
If he lives to ninety, Ben Harvey will always remember the night before Aster Dell.
They'd been happy, all of them. Farah and Saul laughed and danced, there in the light of the campfire. Farah had found a way to make the air itself play music. Ben had pulled out the wine they'd saved for the end of the war. Rosalind had buggered off for the evening and Andreas -
Andreas, for once, had looked at them all with the faintest trace of his old smile, and asked if Ben wanted to dance to the music. His hands were rough - callused from holding his sword, and his grip was reassuring and strong, and Ben remembers thinking that they were going to make it. They were going to end the war at Aster Dell, and they were all going to go home. They were going to go home, and Andreas was going to get the help he needed. Rose would understand. Rose would be the first to volunteer to help. They dance, and at the end of the night, he clings to Andreas and makes him swear to come back alive the next day.
Aster Dell goes up in flames and only one of Ben's two Specialist friends comes back over the ridge, wearing the other's blood.
Ben patches Saul up after the fight, and every other week or so after it without a word. He heals Saul's wounds, and lets Saul cry on his shoulder after killing Andreas, and Ben Harvey tries not to rail at the universe or curse Saul's name. He wants his friend back. He wants all of his friends back, not just the haunted shells they've become, and above all else, he hates Rosalind Hale more than anyone in the entire world until the day Andreas walks back through his door.
Saul will forgive him, he thinks as he sinks into his chair, clutching at the arm as he stares at the ghost standing in his doorway. Saul will understand if he thinks about things for even an instant, and Farah will do the same. They will understand. They must understand.
"Ben?" Andreas asks uncertainly. He comes closer, brows knitted in concern. "Are you alright?"
Saul and Farah will understand. They will forgive. They must, Ben thinks - and then, the moment that Andreas is close enough, he pushes himself up out of his chair and wraps his arms around the friend the universe has just given back to him.
"Don't you ever leave me like that again," he scolds, and feels the moment that Andreas relaxes at last. He buries his face in Ben's shoulder and they cling together for a moment, reunited at last.
"I came back alive," Andreas murmurs. "I came home."
"Yeah you did," Ben agrees. "Welcome home."
