He traced his fingers along the words, carved in stone. The letters spelled a name that he knew as well as his own, a name belonging to a person that he learned to to love. But he would not cry. Not even after all they had been through together, after how much he had loved her, he would not cry.
Severus Snape sighed a long, sad sigh and sat down by the gravestone. Lily Potter, the words said. Lily Potter. He hadn't known her that way, the words sounded more familiar as Lily Evans. Or, the way he had fantasized, Lily Snape.
And they had had a son, Lily and James, named Harry. A son that had survived.
But Lily had not survived.
And yet he would not cry, he steeled himself against the cold dark evil world, because only an evil world would kill Lily Evans.
Clouds were gathering overhead, deep, dark clouds that meant rain. Back in Hogwarts, when there were clouds like that, he and Lily would recite a line from one of her favorite books when she was a child: "Tut tut, it looks like rain".
Back in Hogwarts, before the Incident that would change everything, they used to sneak out and run in the pouring rain and come back in, sopping wet and laughing; and they would use charms to dry themselves off so that the teachers would never notice.
Back in Hogwarts, when everything was wonderful, before the Incident...
Severus closed his eyes and, as it began to rain, allowed himself a blissful moment of remembrance.
When he left the graveyard, his face was wet: From rain or tears he did not know.
