Margaery had noticed the cold as soon as she entered the room and realised that Renly must have been sleeping for there was no way anybody would reside in a room with this chill had they been awake. However she knew her words would rouse him, and when he lit the candle she also noticed she was right about her brother being absent. Though judging from the state of the bed Loras had been there earlier.
She moved further into the room at his beckoning, not hiding her appreciation of his body as he lit the fire. He may be laying with her brother but that didn't mean Margaery couldn't enjoy looking besides he'd be required to do more than look at her soon if she was to give him an heir. She sat in the chair he gestured her too and felt the fires welcoming warmth seep into her chilled skin.
"Our plan for you to claim the Iron Throne was successful and you wonder why I am here?" she said, amusement lacing her voice and her smile open, "I wish to see my king in his rightful place of course. We also have many matters to discuss and our own celebrations to hold" she added with a heated look.
When she had questioned Loras he had revealed his relationship with Renly however, Margaery suspected, he had not informed Renly of her knowledge which meant that she could play for a while. After all one had to take amusement where one could and Renly was so sweet when he was flustered.
