I'll haunt the world inside you.

“She cannot stay here like a leech upon this property. She has neither prospects nor skill, to say nothing of style. She’s a waste.”
You are aware that Sansa is not quite out of earshot, and so is damnable Cersei. It’s regrettable, that you were not able to engineer this scene any other way.
The stone paperweight you dropped from the apex of the ceiling ten seconds ago glances, just barely, against that perfect Lannister cheekbone, and the lady shrieks. Then the paperweight hits the floor with a bang.
The note tied to it by black ribbon is stamped in your usual style, and when the assembly catches sight of the avian skull, a murmuration and then a hush passes through the room. Some heads turn skyward, but you are already gone.
Varys is, as ever, the only one willing to read your missive aloud, and does so with disarmingly good humor:
“Good fortune can spring from the direst beginnings, and ill fate can blossom in even the richest gardens. Management may consider Sansa Stark a charm toward my favor, if it suits you. Above all, she is not to be cast from this place. Fail to heed me, and this House will be razed until nothing is left. I remain, lords and ladies, your humble Opera Ghost.”
Even before he does so, you are on the move, down and down; if you are very careful, you can make it into the hollow section where the ceiling meets the wall nearest to Sansa before….
There is a pause, after which everyone begins to talk at once. Cersei, rallying, snarls impressively over the din, “I will not be cowed by a—!”
You can’t hear it, but you know what’s interrupted her: the paperweight by her feet bursting into flames. It will have scorched her shoes and the hem of her dress. Judging by the noise, it’s sent her spinning, frantic with rage. You hope, for a foolish instant, that it’s made Sansa smile.
In a few more moments, the fire will douse itself elegantly under the weight of its own ashes, leaving only smoke and a charred reminder on the floor.
You put your mouth to the crack in the wall, and you murmur, “Run along now, Miss Stark. Quickly. You aren’t here.”
She goes, and you know she must be yours.
By your own means, you follow.
