"Oh, of course, if only. Silly me," he says airily, and rocks himself forward to spring up to his feet. He stalks towards her, hands and teeth clenched. "I'll have you know that this is my mind and I never invite people in."

Which means he fully intends to "escort" her right back out, except there is a howl of gusting air, and a jagged tear opens through the sky, revealing space and time and pretty much bad memories galore for the Master. He jerks in his approach to her, staring up the sky with a tinge of fear. He then eyes her dully. "You know how they say there's always a safe place in dreams?" He doesn't actually know if anyone says that, but he smirks all the same. "Not here."

He bolts. If she has any sense of self preservation, she'll follow him.
