Okay well it’s mostly for episode two but anyways, you know how Holly was kidnapped by the demogorgon, well what if YN was there since idk YN and Holly are like best friends so what if YN was trying to protect Holly but still gets injured, and in the hospital after Nancy got out the bathroom from washing her hands, YN was released and saw Nancy and then starts crying and starts walked to her and saying sorry abt what happened.
The is my take on this, you can put in like in your style but I figured you might wanna try it and see how it goes.
