I didn't even think," she said and finally took a good look around the house. "Mother of...
Tilly, the manor looks just like it did twenty years ago."
The elf shrugged. "Tilly keeps busy."
Mia frowned, noting that the elf had aged but not very much. Unlike Kreacher, who
had been left to his own devices for years, Tilly was clean and looked sane. "You've been
here all this time alone? Tilly, you should have left."
Tilly shook her head. "Master told Tilly to stay," she said firmly, emphasising her
statement by pointing at the ground.
"Oh hell... Jamie."
Tilly narrowed her gaze and growled. "Mistress must not curse Master," she insisted,
patting Mia on the head like an obedient pet when she looked contrite. "Everyone knows
who Mistress is now? Tilly can speak of it?"
Mia nodded, smiling as she felt the elf's relief. "Yes, Tilly. You can do whatever
pleases you."
"Anything that pleases Tilly?" she asked nervously, twisting her tea towel in her
fingers.
When Mia silently assented, she grinned and turned to look at Sirius and Remus.
Holding out her hand, a rolled up copy of the Daily Prophet appeared in it. Stepping forward,
she began whacking the wizards on the legs with the paper. When she could not reach their
heads, she levitated the paper upward and used her magic to thwap them repeatedly.
"Ow!" Sirius shouted, covering his head with his arms. "What the fuck!?"
Remus winced. "Tilly! Stop!"
"Bad boys! Tilly watches them yell at each other, makes Master and Mistress Lily
sad! Mistress said to trust each other! They's bad wizards! Needs be punished! Tilly spanks
them!" While the paper continued to hit them over the heads repeatedly, Tilly made her
way around to firmly smack Sirius on his arse.
"Careful Tilly, I might like—Ow!" Sirius jumped away from her, grasping his
backside with both hands. "Not so fucking hard!"
"Tilly does as Tilly does!"
Remus had the grace to at least seem apologetic. "We're very sorry, Tilly."
