Facing a zombie as soon as he had stepped beyond the door of his apartment hadn't been something Remus had planned, or ever would, but that was exactly what the windy day had happened to be, and Remus was tempted to just walk back into his apartment and imagine it had never happened.
He didn't, though, because he would never hear the end of it from Lily if he did. She had called him only a few minutes ago, reminding him not to be late, and the promise he had made had become a little more tricky to keep.
Keeping a hold of the shreds of courage, and fear, that lingered somewhere in his abdomen, Remus ventured into the throngs of zombies. He was pushed and shoved through the crowd (none of them realising he was human) until, finally, he was able to walk through his own volition.
"Didn't manage to prepare?" the zombie next to him asked, grinning. He wore ripped clothes with bloodstains, and his hair was a mess of black with bits of stuff in it.
"Difficult to prepare for something like this," Remus stated, wondering how zombies were able to talk if they had their brains eaten. He had only ever read about zombies in fiction books though, and even then in passing, so it figured his idea of them were wrong.
Another zombie jumped the one Remus had been speaking to and Remus thought he heard a groan as the zombie went down, but had yelped himself so wasn't certain.
"Sirius," the original zombie said, "just because we're dressed like zombies, it doesn't mean we have removable limbs."
"I never would have guessed, James. Even I wouldn't eat your brain," the second zombie, Sirius, snarked, before catching sight of Remus. "Now, your brain, I definitely wouldn't mind eating!"
Remus slammed the book he had intended to read on the bus on his head, and the zombie joined his friend on the floor. He still wasn't sure he believed that they were just dressed as zombies: he would have heard of something this big. "I'd rather you didn't."
"Alright, sorry, sorry. Bad joke, I get it," Sirius mumbled. "Or maybe you're the zombie killer. I heard there would be one, I just hadn't expected you to be dressed in a cardigan and carrying a book as a weapon."
A few of the zombies had stopped to stare, giggling, and Remus was suddenly embarrassed. He hadn't expected to cause a spectacle of himself, and he was slowly realising that these two were actually people and not zombies and he had just attacked someone and...
"I'm so sorry," Remus blurted. "I didn't realise-!"
"I'll accept your apology if your number comes with it." Sirius winked, while rubbing his head. "but, wow, you have a mean hit with that book. Do you practice or something?"
