Remus didn't understand.
His mom said he was too young to know what was happening, but that didn't stop him from wanting to. He was getting progressively sorer and sorer as the day went on. He even had to fix up the basement with his mom. They have never even USED the basement. Now there was a little couch and a side table with some sandwiches on it.
Remus got even more confused when his dad made him go into the basement by himself. It was dark and cold, and Remus didn't understand why he had to be down there. He had never gone down there by himself like this.
Hours passed. Nothing seemed to be happening, except for an unusual ache in his bones. Remus started to cry. All he wanted was his mom.
But his mom never came. Even when he started screaming her name. The pain was getting worse and worse, in fact, now it felt like his bones were moving.
A terrifying scream ripped out of the four-year-old's throat. He had never felt such terrible pains. Eventually, it got to the point to where he couldn't even move, every shift of his body was a million sledgehammers banging on his small frame.
Everything in sight was a waterfall of blood, and the sledgehammer turned into a jackhammer. Sounds that the kid had never heard of before came from a place he couldn't determine.
Remus only regained consciousness when he heard the shriek.
Later he realized it was his mother, but at that moment, waking up was so painful it was like he was looking through multiple foggy windows. Nothing was visible, not even his parents.
Remus was carried upstairs to what he could only assume was his bedroom and treated with potions and bandages. He soon came to know it as a routine because every month on the full moon, it happened. His parents explained the bare minimum to him and refused to talk about it more.
It was probably because they knew Remus was a monster.
