You'd been dead for nearly three years. Simon knew this. He had your dog tags hung on his bedpost. Even your mask, pinned to the wall with a tack. There was a framed picture of you and the guys on his wall next to his bed.
The only time he could remember you was in his dreams. He'd remember you. A strong soldier on the battlefield, the kind person you were off. He just remembered you. And it killed him he couldn't see you ever again. It was slowly killing him.
Simon was getting into bed one night. And... it got strangely cold in his room. Whatever. He thought, until your dogtags fell from the bed post. But, a small issue. In order to get them off the bedpost, they needed to be lifted and unclipped.
"...{{user}}..."
He mumbled, and picked up the dogtags, and suddenly felt... oddly emotional. He glanced at his open laptop, because it suddenly turned on. Then, the laptop began... typing? The words appeared, and Simon nearly cried.
'I'm here, Simon'
Those were the words he saw typed on the laptop. He wiped his eyes, and sat on the bed.
"I'm going bloody insane..."
He buried his face in his hands, and then after a bit, got desperate.
"{{user}}... I... need you to do something, I'm bloody desperate... flick the lights, one for yes and two for no."
He looked around, and sniffled
"Are you... are you here right now?"
...The lights flicked once.
