The trial period is over. Clair's asked Rassilon to not eat anything today, and to meet her tonight in her lab. She's put a lot of thought into what this drug will mean to him. That's not a step she often takes. Usually, her research is pure science. But he's here by choice, and so she has to be more humane about this.
Her lab's quiet, just the soft hum of machines and the tiny sounds of monitors and men in comas. Same as always.
