Sirius could never think of a way to freak Peter out. Sure, the guy got scared all the time, he was timid, but that wouldn't count at all. To scare Peter had to be something that would make him lose sleep or to quiver for it to count.
It was strange; he would have thought that Peter would have been the easiest to freak out, there was no question about that, it just didn't fit that he would be the hardest.
Then again, he thought he had known Peter as well as the back of his own hand until James and Lily died.
He had tried many things, he had hummed the 'Jaws' theme whilst sneaking up on him in his beloved werewolf costume while Peter sat innocently on the couch. He had described his sex life in great and gory detail. He didn't even get a little jumpy when Sirius had printed off hostage notes and left them all over Peter's room. He had even done the more classic sort of pranks, like dungbombs hidden on the bottom of his shoes, cheesy, yet entertaining. Nothing had worked, nothing would ever work, Peter was a solid wall and nothing could penetrate him.
Well, that was until 14 years after he had made that New Year's resolution. In fact, he didn't even scare Peter on his own, Remus helped.
It was rather funny that it happened in the Shrieking Shack. For one, the local residents always thought it was haunted, from Remus's cried and wails that echoed through the village every moon. It was ironic that it was the home of so many of the Marauders fondest memories, considering that t was thought to be a Godforsaken place. In a way, on that night in June in 1994, the Shrieking Shack was finally living up to its infamous name.
Sirius, his face gaunt and waxy, his eyes sunken, was aimed to kill. He was killing two birds with one stone, he would be able to finally scare Peter out of his wits and avenge James and Lily's deaths and finally be sentenced for the murder he should have committed.
Remus, his face strangely content and happy, something that had not truly been seen on his scarred face in 12 years, was just ecstatic to have Sirius back by his side, his head already refilled with images of Sirius and himself growing old together in a little house in the country. He just wanted to help his two best friends rest peacefully in their graves knowing that the man that put them there was gone.
It was the least he could do, given that his condition made him automatically less able to be their Secret Keeper in the first place.
That, and no one had trusted him.
Trust is a bitch.
Both posed with wands, they grinned like the wolfish animals they could transform into as they opened their lips to utter the two words that would end Peter's miserable little life.
Peter's face was washed of the little blood that had been there in the first place, his lips were pathetically quivering one word, "Please, please, please," he said, over and over again, as if he could do something to make it all better now. The fool, nothing could be done now, nothing will ever bring Lily and James back for them all, for Remus, for Sirius and Harry.
Sirius drew a long breath, like that cigarette he took when he ran from his parent's house, and he wanted to drag this moment out, drag out Peter's final moment, and to savour and taste Peter's fear. Just like James should not done have had before he died in a last and desperate attempt to protect his family. And just like Lily, who died terrified, yet still protecting Harry.
Everyone had someone worth dying for, or at least a cause.
Why didn't Peter?
Peter had nothing like that to live for, no wife to love or child, now he never would; he did not deserve any of those things. And those three knew it.
Sirius knew he had accomplished his goal then and there.
His mouth pulled itself into something of a smile.
Peter was positively terrified and beyond freaked out. Excellent.
