The TARDIS spares the two a glance, rather sad that her and Johnny's interactions can't be as simple. His explanation isn't exactly clear, but she gets the feeling he couldn't make himself understood any better if she asked him to elaborate, so she just nods.

"The rift has affected the physiology of some people as they came through," she muses, "it might have radically increased a pre-existing psychic sensitivity to my physical properties. You clearly aren't affected by my mental presence." That's something, at least, and she tries very hard to think of a way to mitigate the effect in the waking world as well.

"Perhaps if you learned not to be scared of it... of me." She can't help sounding slightly dejected at that; providing for people's needs is a fundamental part of her nature, and being a paradox to someone's senses is kind of horrifying.
