Aberforth snarled, unhappy that he could not use his magic during the summer. Without his magic, he decided hurtful words worked almost as well. "Hey, Albus, your boyfriend is here!" Aberforth yelled out as he headed toward the basement door to take care of Ariana.
Before Aberforth made it downstairs, he noticed that Gellert had momentarily paused on the doorknob of Albus' room. The pause in movement was so slight that Aberforth almost did not catch it.
Gellert entered to room, and there was a click when the door closed. Aberforth gaped for a moment, wondering if his jab at Albus' heterosexuality was true.
Aberforth shook his head as he went down to the basement. If the they were actually dating, Aberforth did not want to know what they ACTUALLY did in that locked bedroom.
