A/N So this is just a tiny Severus/Lily oneshot that popped into my head the other day. Enjoy!
He saw emerald green eyes and it was the end. They were the emerald green eyes of Harry James Potter, standing over him as he died, then chasing him angrily across the grounds, then glaring at him, and finally seeing him for the first time and, oh, the shock that those eyes gave him. They were the emerald green eyes of Lily Evans, empty, then filled with love as she looked up at Potter, then filled with hate as she looked at him, then protective, excited, and happy to see him.
He woke up.
The eyes were still there, staring down at him. Lily. She pulled him up, smiling. He stared. She was perfect. This was Lily as she had fought in the war, not his Lily, and yet she was still smiling at him; accepting him. She looked at him seriously.
"Thank you."
He nodded his head. He knew she was still with Potter. He knew she would never love him as he loved her but somehow her gratitude was enough. It didn't quell the pain of the last sixteen years, or the five before that, but it made them worthwhile.
She offered him her hand. He took it and the two of them walked on, together.
It was enough. In Lily's eyes he was no longer a filthy death eater, a traitor, a killer or any other label he'd ever been given. He was her Sev. Always.
