She offers gratitude, money, and her daughter's flower to kill King Joffery

Olenna stares with her great gray eyes as her old wrinkly forehead scrunches. Her voice came out still forcing respect to be known to her. "I will offer you my deep gratitude, and appreciation for that blue venomous rock. As well as gold from the vaults of my son. And to sweeten the pot, my daughter's flower can be yours later tonight, if you hand over the pebble to me."

You look her over as if she was an older lady but still had some beauty. "I'll take the gratitude and the gold from your vault." You grin rolling the stone in your hand, passing it back and forth like a basketball. You don't need an old lady commendation or the massive amount of gold at the Tyrell keep. But the idea of fucking Margaery did sound like a wonderful deal. You thought about keeping the Lannisters strong. Let the crazy bastard wreak havoc as you grow from behind the scenes. The realm feared the man in the shadows while the king ruled them.

You nod, as the old rose's lips form a slight smile. "Good choice, my lord. Now, if you'll excuse me, I must go mingle with the other guests. Please, do enjoy the feast and the dancing."

"Ah, don't worry Olenna, the festivities will be fun." You reply with a wicked smirk to keep her attention. "I already know that flower has been spurted on by a few bees a few times." To have more eggs in the baskets and keep all your options open you use your powers furthermore. "Take this poison. But don't use it until I throw a wink at you. Only if I throw a wink, is the time you shall know that I approve of your plan. Do you understand?"

"Yes." A glossy look upon the elder Tyrell's face as she mutters her agreement to your words.

You pat her on the shoulder as her old body moves toward the feasting. She was no longer her person as her mind was completely under your control. For a small amount of time at least, you thought.

As the feast starts, you can see the excitement and anxiety among the guests. Your eyes scan over the room as the young king is seated. Cersei was sitting next to him, her face full of disdain at the thought of her son's marriage. You could feel the tension in the air as everyone waited for the entertainment to begin.
