“Oh, there's always a reason why. Control, leverage, or maybe whatever it is just got bored. Remember little Chloe Webber? All those neighborhood children, sucked into the scribblings of an eight year old girl, all because a single, lost Isolus was lonely,” he mused, the reminiscence bringing a quiet moment of reflection. The Isolus had been their last adventure together before everything had gone pear-shaped and they'd lost each other for the first time.
However, instead of dwelling on the things he couldn't change, he placed his attention back on the present and set to thinking aloud as they ventured closer to town. “But the question I'm more interested in is the how, not the why. Could be like the Bermuda Triangle, unsuspecting travelers passing over a particularly sensitive magnetic abnormality and before they know it, they've disappeared only to reappear in a completely different location than the one in which they started,” and with that he reached into the breast pocket of his overcoat and withdrew the sonic screwdriver with his free hand, flicking various settings with his thumb and briefly scanning the area.
“Probably not, though, bit of a stretch, that. Margin for error's too big,” he muttered, frowning slightly when the device in his hand returned perfectly normal readings outside of a slightly elevated level of temporal energy, which was to be expected.
He pushed hot air through his nose in mild frustration, pocketing the screwdriver and beginning to gently swing the paired hands between them as they walked. “Whatever it is, it seems to be selective, because if it were simply random chance, I find it unlikely that you, Jack and myself would just pop in on a very lucky whim,”
And perhaps someone else, if fate held him in her favor.
