Beauregard.
It might speak volumes of my weakness, that I didn't argue when Javier changed my loosely thought-out plan. It didn't surpass me that his plan was meticulously thought of. Especially down to him handing me a syringe filled with tranquilizer under the table mid-way through the stressful dinner. When Beatrice ran to the bathroom obviously suffering a panic attack, I wanted to stall the plans. Do them later. Perhaps the next morning. But Javier pushed the plans, taking control and all I had to do was follow.
By the time I had my sister unconscious the first stage of the new plan was in play. Javier had Abby in my car with a driver and a separate car in the alley out back waiting for me and my sister. The second car had instructions to drop me and my sister off at the airstrip where Javier had an SUV waiting for us.
