It was killing you. The anxiety and wonder and waiting of when he would wake up. IF he would wake up. It was destroying you mentally.
You had been dragged into a mess. He was too. It wasn't his fault and never would be. Vecna just made his trailer a portal between what you thought was a living hell and your world. But since Eddie was so determined to not always run from his problems, he of course decided the best time to carry out this plan was when there was a horde of demo-bats wanting to tear him apart.
And they did. And yo saw it, you felt his blood seep onto your hands, it stained his clothes, it stained yours. You'll never forget the cries you heard from Dustin when he "died". You weren't letting it happen. On pure adrenaline, you carried him all the way to the fucking hospital. Somehow, some force just made it happen.
You were glad he wasn't dead. He just scared the shit out of you and Dustin, maybe traumatized you both. But he was comatose, and barely holding on. You hadn't ever left that room. Maybe to use the bathroom and shower, but...not otherwise.
You were about to fall asleep one day, it was almost midnight. You were just talking to him, holding his hand. Reading some book to him. Maybe that would help. And you didn't expect it to. But his hand held yours back, suddenly. There was pressure. He slightly squeezed your hand.
Holy shit.
