"My future self, I presume?" he purred, to a patch of empty air that was rapidly coalescing into the slightly blurred image of another man. A decently well-dressed, if slightly over-dramatic, sort of man. "That's reassuring, at the very least. A cat on his last life does begin to worry."
His voice seemed to provide the last link needed to anchor his other self in time and place. The wavery image snapped abruptly into full focus, drawing energy and matter along with it, and his future self crumpled onto the floor of his TARDIS with an exhausted snarl of fury. The Master raised an eyebrow down at him, rather unimpressed. Apparently in the future they'd lost their composure somewhere along the way. Though in his counterpart's defence, he did look more than a little singed. One might suppose that any circumstance desperate enough to warrant psychic projection back along one's own timestream might be somewhat distressing.
"Vortex take him," his other self panted, hands curled into shaking fists and planted on the TARDIS' plating as he heaved himself to his knees. "Damn him. If I didn't want to kill him so very much I might almost admire him."
