Together Forever

"Hey, what's wrong?" Dustin softly questions the crying boy, gently grabbing his shoulder and rubbing it to try and soothe him. He doesn't respond.
"Will, if something's wrong, we want to help you. You're our friend, and you mean so much to us, so please, let us help you." Mike pleads. Will turns to the pleading boy and his doe eyes meet Mike's inkier ones. The former flits his eyes away before taking a deep, shaky breath.
"I think... he's coming for me." He says, barely above a whisper, his voice blending with the gentle breeze of the air.
"...Who? Who's coming for you? Will, what are you talking about?" Dustin rushes his words in a rising panic. Will just shakes his head silently.
Neither boy needs Will to clarify what he said.

Summary:

Will is cursed by Vecna, but he doesn't tell anyone until Vecna's ready to take him for good.
