Some of those descriptions of the oddities and burps in time ring familiar but most don't, and Daniel has no doubt that he's somewhat reduced in his ability to conceptualize much of it. The science and specifics of time travel have never been his area of expertise. Number-related matters in general will always be beyond him.

"That is," he says with an astonished grin when the Doctor stops for breath, "wow. I mean, really, wow. I've, I've traveled to other planets and phase-shifted and even, even occasionally breached into another dimension or universe but, uh, but time travel? That's, that's just incredible. We've managed it maybe twice." Possibly three times, if that one report on time loops can ever be conceivably, reliably verified. Maybe four. It's confusing without outside confirmation.

"How, though?" Question number two already, and Daniel can hardly keep it at just that. "We've used solar flares, a ship once, but those were very, very one-time affairs. How do you manage that sort of thing regularly?"
