Ash knew what those letters were. Especially if Bella was coming to speak to him about letters. He made a disgusted noise and then said, "I'll be right back, guys." He rose in a single motion with entirely too much grace mixed with something more predatory. Quinn shrugged his shoulders and turned to say something to James, the two already continuing their conversation to allow Ash and Bella to go and chat.
He didn't say anything to Bella, just pointed in a direction and walked until they were in a more secluded part of Slytherin dorms. He leaned against a wall and folded his arms, "I already told your dad to mind his own fucking business. I've never met a father so blunt about having me fuck his daughter."
