Whispered Prophecy
The Great Hall went silent as the most rarely seen professor entered and made her way delicately between the house tables towards the other professors. Trelawney peered through her thick spectacles at the teachers before her. Suddenly she looked straight at Severus Snape and moved towards him. Despite having the huge table between him and the considerably unhinged Divinations professor, Snape tried to push his chair away and escape. Sybil took no notice of his attempt to get away and finally stopped before him. Her gaze pinned him to his chair and she leaned close over the dishes and silverware.
All of the students watched in curiosity as the snarkiest professor in Hogwarts history couldn't extract himself from his strange coworker. They could see she was speaking to him and his brows knit in confusion, but no one could over hear the words despite the deathly silence of the room. Not even the professor immediately to Snape's left heard the words. It were as if someone had drawn a soundproof curtain around the pair.
"I am aware you do not like me Severus, nor do you put any stock by what I say, but hear me. Listen, for it is important you know what I would tell you. You will not die when you expect, though it will seem as though the end of your world and you would welcome it. Dear Lily will see what I have seen and send you back to be happy with the one who has the power to heal you."
Trelawney cocked her head as if listening to the silence and then smiled knowingly at the potions master. "She is here now."
She suddenly grabbed a chicken leg off his plate and released his gaze, tottering out of the Great Hall and presumably back to her stifling tower. The moment the door closed behind her, all of the students and teachers began talking, nudging neighbors and pointing surreptitiously at the head table. Realizing that Sinestra on his left had not heard the seer's words, Snape shoved his chair back and fled to his office to put the strange conversation out of his mind. And he successfully did for several years.
By the end of that year, Voldemort had returned, Snape had been called back into service, and he returned to the tricky balance of playing a double agent. Umbridge made his life even more miserable, compounded by Potter and his friends. The next year was even worse as he was forced to end the man he respected most. Blessedly, Potter and his two sidekicks were absent for their 7th year, but Voldemort pressured him even more.
Just when he felt he was about to break, the final battle was on his doorstep and fighting didn't take any thinking. Severus turned his wand on any and all Death Eaters, relieved he no longer had to play both sides. He was sure he would not leave the battle alive, and that was confirmed as Nagini sank her fangs into the soft flesh of his neck and shoulder.
