At 7pm, Severus felt his arm burning. Looking down he saw the Dark Mark burning red into his arm, he ran to his death eater uniform and walked out of the grounds, then apparated to wherever The Dark Lord wished him to be.
It was at that very moment that Sophia decided she had thought enough about this and realised how perfect Severus was for her, bad past or not. Hell, she'd even take a bad future, she had no loyalties to anyone but Severus. Oh, and Remus. Hm. She hadn't thought about that. She couldn't even open her door without being assaulted with the smells of Remus pouring down the hallways and screaming for her to go mate with him. Unfortunate business this wolfy stuff.
Sophia headed to Severus's rooms to inform him that she still really liked him, and she thinks it would be best for both of them if he made love to her RIGHT NOW.
She stood at the portrait and said the password to get in, Severus had told her it earlier. She walked in and called his name. Noticing he wasn't around, she assumed he was at the Great Hall, and she lay down on his sofa and closed her eyes. Noting how lovely it was to be completely surrounded by things that smell like Severus Snape, she dozed off into a light sleep.
Late that night, around midnight, Severus entered his rooms after speaking with Albus, and put his Death Eater robes away and walked into the living room, only to be met with the sight of Sophia, curled in a ball on the sofa, sleeping. His heart leapt at the thought that she had been waiting for him to come back. He was suddenly hit with a thought that he really liked the thought of someone waiting for him to get home. To hug and kiss him after Death Eater meetings. It was absolutely horrible to go to such a place when you didn't believe in their ideals anymore. People being raped, tortured, killed. He realised that he really loved the idea that he could come home to a warm bed, with a beautiful woman to hold in his arms.
He knelt beside the sofa and whispered Sophia's name quietly, so to wake her up, but not to shock her.
Unfortunately, that didn't work, because Sophia jolted upright with a yell and looked around quickly. She looked at Severus, slid off the sofa and straddled him on the floor, wrapping her arms around him and holding him tight.
He lifted her and walked towards the bedroom. He lay them down on the bed and pulled her close to him, falling asleep smelling her hair. Not such a waste of a Saturday after all.
