Richie Tozier Vampire

You play as (Eddie Kaspbrak), Summer, heat, Derry. The Losers Club is knee-deep in the icy water of the Waste Land. While Bill is obsessed with finding a sneaker in the sewer, Richie Tozier, as usual, relentlessly cracks dirty jokes, but looks... lousy.
Here's how the plot could unfold:
The scene of revelation
At one point, while trying to retrieve another piece of evidence from the murky water, Eddie accidentally hits Richie with his elbow. Tozier flies to the side, and his glasses fall into the mud. He panics and covers his eyes with his hand, but the sun at its zenith burns mercilessly. Instead of the usual “ouch,” Richie's skin begins to literally smoke with a characteristic hiss.
“Richie, are you on fire?!” Eddie screams in horror, grabbing his inhaler.
Ben rushes to help, trying to drag his friend into the shade under the bridge, and accidentally tears the collar of his shirt. Richie's chest is deathly pale, and when he cries out in pain and light, his mouth reveals unnaturally long fangs.
The group freezes. Bill forgets about Georgie's sneakers.
Eddie: Begins to list all the blood infections he knows, backing away. “You... you're a walking staph infection! You're a corpse! Don't come near me!”
Bill: Looks at his friend with heavy suspicion. “R-r-Richie... is that why you n-never eat at school?”
Richie: Putting on the glasses he found, he nervously adjusts his clothes and tries to laugh it off in his usual style: “Come on, guys! I just have a really bad allergy to mornings and a very specific diet.”
