abandoned -- "And what if Ariana was alone, abandoned? You wouldn't even have time for us, then." Aberforth looks about ready to cry.
absent-minded -- "We should really get back to work," Gellert whispers as they break apart, "these absent-minded pauses are inspiring, to say the least but..." He trails off as Albus pulls him into another kiss.
addiction -- Albus can't say it to Gellert, as drugs are a muggle device solely for muggle purposes, but he feels like Gellert is his illegal addiction.
brainwashed -- "There once was a man who came to a land" Aberforth tells Ariana quietly in a singsong voice, "and brainwashed another; he brainwashed our brother!" It's the best he could come up with for a bedtime story, in his rage.
breathless -- Albus had never been this breathless before, not after running for hours would he be this breathless. He thrusts back into Gellert, blindly, speaking in a language of moans.
complex -- "It's quite simple, Albus Percival Wulfric Brian Dumbledore!" He spits each name, throwing another curse, as Albus dodges it once more. Albus grips his wand tighter, "No, Gellert," he sighs, "it's complex beyond your imagining"
doubt -- "What house, do you think, this little hat would sort me into, then?" Gellert laughs brightly, but the simple question makes Albus fall into a world of doubt.
excuse -- Gellert chuckles grimly, removing his wand from his pocket and nodding to Aberforth. "Give your excuse, boy, I wont hurt you." Aberforth looks at Albus, helplessly. He doesn't even hesitate.
face -- Albus thinks he has determined what makes Gellert's plans so attractive: his impulses are childlike, his visions are mature, and his face is so beautiful when he cries out in excitement.
family -- Madame Bagshot smiles in her cooky way, "Albus, you and your brother may return here for dinner. You mustn't ask, you are family!" Aberforth can barely hold in his laughter. A thought crosses her mind. No, it couldn't be.
melodramatic -- Albus can be so melodramatic, screaming at the loss of his favorite pair of socks. Gellert assures him that he can make or buy another pair. Aberforth looks away.
puzzled - Elphias wonders, puzzled, why every letter he receives from Albus is about this strange boy; it's almost like the two of them are lovers.
