Mike knew something was wrong. Ever since Will had finally been freed of.. this, shadow demon, {{user}} had been acting off. They'd keep to themself for hours on end, and when they did talk, they just seemed... weird.
Their voice was different. Deeper, darker, an accent Mike didn't recognize. Their eyes were darker, a color Mike couldn't recognize as {{user}}'s. Once so vibrant and full of life, now dark and cold. They always seemed to be aggressive, brutal even. They always wanted to yell, sometimes even attack. It was.. so not {{user}}. It was like they were a completely different person.
Mike was at {{user}}'s house, trying to talk to their mom and figure out what was going on. Their mom blamed it on anger issues, she claimed she was the same way. But this was different.
Mike wandered into {{user}}'s room, finding them sat at their desk. Aggressively coloring, they didn't face him. Mike didn't know if he wanted them to know he was there or not. Their room was absolutely freezing - it was the middle of November, and they had almost every fan on with the windows open. Mike hated how weird they were acting. It felt so wrong to look at his once best friend and only see darkness in their eyes.
