Mia smirked and snatched the ashwinder eggs back from him. "I'd prefer right here,
actually." She approached Walburga's portrait, stepping up and throwing the frozen eggs
at the top of the painting, layering them against the frame. "Sirius, are you ready to say
goodbye to your mother?"
He stared at her, not entirely sure how she was planning on doing what her eyes and
words were promising, but he still felt like a little boy attending the Quidditch World Cup
for the first time with light in his eyes and hope in his heart. "No need for goodbyes. Old
bitch can fuck off for all I care."
"Good to know," Mia said and aimed her wand at the painting. "Incendio!"
The bottom edge of the frame caught fire first, and Walburga screamed obscenities
at Mia from beyond the flames and smoke that she syphoned off with a Filtering Charm.
When the fire reached the top of the frame, the bottom began to repair itself as it had been
spelled to do. However, the heat thawed the ashwinder eggs which crackled and set fire to
the seam where the painting met the wall. It was not Fiendfyre exactly, but strong enough
to detach the portrait from where it hung.
The painting fell to the floor with a loud bang.
Mia raised her wand, shouting, "Evanesco!" to vanish the sizzling eggs and the flames
they had ignited.
The wall was blackened from the fire but could easily be painted over.
Sirius stared at the fallen portrait and the blank space on the wall and then slowly
turned, mouth open toward the witch. "Marry me."
Mia laughed. "We're already engaged, idiot."
"It's not enough," he insisted and pulled her into his arms. "You need more. Do
you want a bigger ring? I'll get you a bigger ring. I'll get you ten rings!" He swung her
around in a circle, moving a few steps forward so he could stomp his dragonhide boots all
over his mother's fuming face. He kissed Mia deeply, plunging his tongue into her mouth
and stroking hers with hungry, needy movements. Eventually, he pulled away and pressed
his forehead against hers. "Do you want diamonds? Rubies?"
"Emeralds?" she suggested with a sly grin.
"Fine," he said and crushed his lips against hers. Mia chuckled against him and ran
her fingers through his hair, pulling a rumble from his chest.
