A short drabble I wrote a couple of months back, not sure I liked it, though.
"I saw you two together, last night". Gilderoy said, measuring his words. His voice was shaking a little; so were his hands. "You and Barty, I mean. Sneaking out in the middle of the night..."
Regulus turned around slowly. His fingers were pressed fiercely against the book in his hands when he saw the look on Gilderoy's face, the sight of his bright, blue eyes sending chills down his spine.
"It's not what you're thinking", he tried to say. "Gild, it's not-"
"Don't", Gildery said, with a gesture of his hands. "Don't even start with the apologies. I'm sick of them. It won't work anymore - we won't. It... we... are over."
The young ravenclaw left, crossing paths with Bartemius, who had listened to the fight outside the empty room. The slytherin smiled when he saw the tears Gilderoy tried to hide.
"I told you, keeping what we do secret wasn't going to do well to your... relationship." He bit his lower lip, his hands on Regulus' shoulders. "But sacrifices must be made in the name of the greater good."
Touching the Dark Mark in his arm, Regulus shook his head in agreement. He knew he would have to make sacrifices – but no one had told him they would hurt so much.
