Severus Snape didn't care. He didn't.
It truly didn't bother him that the Granger girl no longer answered any of his questions. It didn't bother him that she never looked him in the eye. Or that she was nothing like the girl that he had called an insufferable know-it-all in the past. It didn't matter to him that the one student who had always put up her hand as if to prove her worth no longer even looked up from her desk when he asked a question. In fact, he was happier this way, no more annoying little Gryffindor interrupting his classes. He was Severus Snape and it most certainly didn't bother him that not even Draco Malfoy teased the Granger girl anymore. Or that no one ever said that horrendous word 'mudblood', because it had been brutally carved into her arm, and was in plain view for all to see.
And no, he didn't feel a rush of shame every time he looked at it.
He most certainly did not respect Potter and Weasley for the gentle protectiveness that they continuously gave to the Granger girl without a thought. Nor was he impressed by the dangerous power that crawled behind Potter's eyes every time someone so much as commented on her scars. Severus did not think about how Potter, who weighed about as much a starved house-elf, always kept energy bars in his bag, of which he would give to Hermione, no Granger, throughout the day. Severus didn't find it touching when Potter flat out refused to play in the Quidditch game against Slytherin because "Mione had a fever and he wasn't going to be anywhere but with her."
Severus Snape did not think that the fact that the Weasley boy suddenly spent most of his days in the library, just sitting in quiet companionship with Granger, was anything notable at all. Nor did he think it peculiar that Weasley could often be seen reading books such as Pride and Prejudiced or Hogwarts: A History; which he had once overheard Granger saying were her favourite books. He didn't get a lump in his throat when he noticed that Weasley never once complained about the fact that Granger was always touching him; holding his hand, or his shirt, or when she made him stumble by twining her fingers through his belt loops.
Severus didn't care that the Granger girl, and by extension Potter and Weasley, skipped his class as often as she showed up. He didn't notice that she trembled every time he stood too close to her. He obviously didn't realize that the colour of his robes reminded her of the death eaters, and that was not the reason he started wearing deep grey instead of black. Severus also didn't spend four hours oiling and cleaning the window in the back of his classroom that hadn't been opened in 300 years so that sunlight would shine on the desk she preferred. He also didn't start lighting the fireplace in his office then leave the door open so the heat would transfer to his classroom because he noticed that she was prone to shivering.
They had won the war and Severus was the happiest he had ever been, nothing else mattered. Severus Snape didn't care. He didn't.
