"HEY. I'm not gay!" Hugo didn't like labels. He really, really didn't like them. He wasn't with Scorpius because he was gay or straight or anything inbetween. He was with Scorpius because he'd fallen for him. Not what he was, but who he was.
"And why does it matter if I'm gay or not. That doesn't change who I am!" Hugo could feel himself getting defensive. He'd already been through this once with his parents and this felt oddly reminiscent of that argument. "I'm sorry I didn't tell you right away, but I didn't know there was going to be anything to tell!"
