Thanks for the reviews guys !

Hermione sighed as she leant her elbow on the desk, running her fingers through her hair. She frowned at the book she was reading and rubbed the quill across her lip, deep in thought. It was dark and way past curfew, but she was still sitting in the library, trying to do her Transfiguration assignment. She was so deep in thought that she didn't hear the opening of the door, or the rustling of a cloak, or even a sound of footsteps heading towards her. She slammed the book shut in frustration, swearing as she did so.

"Language, Mrs Snape," a silky voice said behind her. She jumped up and spun round.

"Professor….I'm sorry, I know it's after curfew, I just….I was trying to get a Transfiguration essay done," she said to him, waiting for his reaction. He headed over to where she was standing and glanced down at the book she was reading.

"Advanced Transfiguration?" he smirked, amused. She really is ahead in everything. "Well Mrs Snape, why were you swearing in that un-lady like fashion?"

"I….I couldn't figure it out," she whispered, sighing defeated. Snape had to struggle to hold back a laugh.

"The know-it-all has finally found something she doesn't know?" he said in mock shock, but his voice held a strange teasing quality about it. Hermione glared at him, which just made him even more amused.

"What exactly is so difficult that you feel the need to curse like Salazaar Slytherin himself?" he asked, as she blushed.

"I…can't understand the concept of transmigration," she said quietly as he fingered through her book.

"Hmmm…Transmigration….." he said, frowning in thought as he skimmed through the page. "when one being can move into another being without physically needed to turn into it, just needed to enter it to control it through the mind?" Hermione nodded, and widened her eyes even further when he started to explain it to her.

An hour later, they found themselves sitting side by side in chairs, Snape with his legs lounging on top of the desk, and Hermione leaning against the seat of her chair, legs crossed, hanging onto every word he was saying.

"Understand Miss Granger?" he asked as he closed the book in his hands and placed it on the table, then turned to face her. She nodded, in awe at how easy he made it sound.

"Thank you so much Professor!" she said, smiling at him warmly, only to see him return her smile. He caught himself in time though, and cleared his throat, standing up. "Good, then we should be heading back to our chambers. 20 points from Gryffindor for being out after curfew."

He then started heading out of the library, but paused, waiting for her to follow him. Instead of taking offence, she smiled instead. Of course she couldn't forget everything he had done to her, but hopefully, they would be able to develop an understanding, and things were looking brighter. They walked to their chambers in silence, and soon reached them.

"Good Night," Snape said as he turned to retire to his chambers, but he was stopped by a soft voice saying, "Professor?"

Snape turned back to face Hermione and lifted a questioning brow. "Yes Mrs Snape?"

Hermione smiled a true smile and said, "Thank you." Snape simply regarded her for a while and nodded, before turning back to his room and closing the door. Hermione smiled. If I'm stuck in this marriage I may as well enjoy it.

Behind the closed doors, Snpae leant against the doors, smirking.

The plan is in action.
