First, give her the brooch

"Queen Margaery," you say reverently, as you kneel before her.

"Be at ease John," she says, "this will not need to be an extensive discussion."

You quickly rise to your feet, your eyes drinking in the sight of Margaery standing there. While still not in quite the best of royal fineries, her low-cut red gown and crown still made her appear much more regal than that night you had found her in the snow, in a flimsy white slip.

"Before I make my request, I would like to give you this gift I have purchased in King's Landing," you say, producing the brooch from your pocket.

The queen looks on warily as you reach into your pockets, but her face lights up when she sees the brooch in the style of House Tyrell.

"This is fantastic," she says, taking the brooch from you, "I always try to find these sorts of markers of my house."

"You are most welcome, your majesty."

"Now then," she says, smiling, as she puts the brooch down on her desk, "what did you want as your reward from me?"
