John Taylor's powers (The Difference A Day Makes)

Another example of John's gift granting him precognition:

I backed up as far as I dared, herding Liza behind me, and fired up my gift. My inner eye snapped open, and immediately my Sight found just the right places for me to stand, and where and when to dodge, so that the robots couldn’t touch me. Their blocky hands reached for me again and again, but I was never there, already somewhere else, one step ahead of them. -The Difference A Day Makes

John uses his gift to find and rip out the control mechanisms located within several robots:

I concentrated, forcing my inner eye all the way open, till I could See the world so clearly it hurt. I scanned the robots with my augmented vision, struggling to understand through the pain, and it didn’t take me long to find the robots’ basic weakness. They had no actual intelligence of their own; they were all receiving their orders from the same source, through the same mechanism. I moved swiftly among the robots, dancing in their blind spots, yanking the mechanisms out, one after another. And one by one the robots froze in place, cut off from their central command, helpless without orders. They stood around the metal room like so many modern art sculptures . . . and I sat down suddenly and struggled to get my breathing back under control, while my third eye, my inner eye, slowly and thankfully eased shut. -The Difference A Day Makes

John states that he can find a way to enforce amnesia as well as ensure that memories stay repressed:

“Can you do anything for her?” said Dead Boy. “We’ve got to do something, John. We can’t leave her like this.”
“You always were a sentimental sort,” I said. “I know a few things. I’m pretty sure I can find a way to put her back the way she was, when she came to us, and this time make sure the memories stay repressed. No memory at all, of the Nightside or Silicon Heaven. I’ll take her back into London proper, wake her up, and leave her there. She’ll never find her way back in on her own. And in time, she’ll get over the mysterious loss of her husband, and move on. It’s the kindest thing to do.” -The Difference A Day Makes
