"What does she want me for?"
Dread filled him. If the house-elf knew that Mia had been in his room that night,
who was to say the rest of the manor didn't? He knew that Silencing Charms had been put
up, but what if they had not held?
"Not time to be explaining." Tilly reached down and untangled Sirius's leg from the
sheets. She pushed him to stand, shoving him toward the door. He was tempted to dig his
heels into the floor to delay the inevitable. "Young Master should be up and going. Go, go,
go. Tilly will take you."
"All right, you pushy elf!" he grumbled and finally took steps of his own free will
when she began shoving her tiny hands against his backside to get him to move faster.
He reached behind, shooing her away from him—which only earned him a hard
swat on the arse. He growled in his throat defiantly but ended up just walking faster toward
the library in an attempt to evade Tilly.
Unfortunately, he had forgotten that, in his desire to escape the house-elf, he was
speeding along toward Dorea Potter—a Black, a Slytherin, and the mother of the girl he'd
just shagged.
"Ah, there you are, dear. Good morning." Dorea smiled brightly as he entered the
room, which immediately unnerved him.
Growing up, he learnt early that it was a flip of the Galleon when it came to the
personalities of the House of Black. One side was volatile, hot-tempered, and easy to
provoke: Bellatrix, his mother, and—unfortunately—even himself. It was the other side of
the coin that was worrisome. Narcissa, Andromeda, and Dorea had perfected the stone
wall that hid away their true thoughts—a smile to hide the serpent's fangs.
"Tilly, thank you so much for waking him." Dorea beamed at the little elf and then
gestured for Sirius to take a seat, smiling even more brightly when he obeyed without
question.
"Young Master Sirius was already awake." Tilly smirked, scrutinising him. "Tilly is
surprised."
"As am I, Tilly, as am I," Dorea said to the elf as though Sirius were not in the room.
"Especially considering the hour my daughter left his room this morning,"
Sirius bowed his head into his hands, peeking at the witch through the cracks in his
fingers as he groaned. Fuck.
