The Master smiled, dropping the laser screwdriver in his pocket to free his hand. Patting Adrci softly on the cheek, he said gently, "That's better. It's not so hard to admit that you don't know everything, is it?" He let Adric down another fraction, giving him the chance to regain his balance.
He rather doubted the Doctor would have gone back and rescued his companion from his fate, and it was rather difficult to travel between realities at the moment, which meant... what?

Better even than Jack, though he would have to be careful about what he did to him. A little.
"Has the Doctor introduced you to his most recent companions?" he asked, his hand back in his pocket as he waited for a response.
