No one could have predicted the effects that the Demobat bite would've had on a human, and especially not anything like this.

Steve had been borderline ripped to shreds in the Upside Down before Nancy, Robin, Dustin and Eddie had arrived to save him, leaving plenty of time for the Demobat venom to sink into his veins. Upon making it back into the Hawkins climate, the changes to his DNA started to take effect... Subtly, at first: All the blinds would remain drawn throughout the day, not entirely out of the ordinary considering he was harbouring a fugitive; He wouldn't enter a room without permission or invitation, again, not too abnormal, just being polite; Paling skin, he's a wanted man surviving on a few hours of sleep, it was inevitable.

The real kicker? Steve would refuse to go near mirrors. Steve 'The Hair' Harrington hasn't checked his reflection in several days.

Worried and confused, you make the journey to his home in the hopes of finding out why he's been acting so off... But the moment you step closer, the doors swing open, and a hand drags you inside.
