Why did he believe it? Well, there was only so far coincidence could go. He pulled the strings and mastered the pied piper’s flute, so of course he could get a sense for when his were being pulled, and he was being played. The only reason he thought it was something of a higher power was because the outcomes had never been bad: they had always held his hand and prompted him to a better outcome. He knew better than to believe anyone powerful in the real world would help him out without expecting some quid pro pro.
Frankly, this gave him some reassurance: a safety net. He never truly relied on it, because to do so was a risk, and Q did not take risks. A risk implied he didn’t know an outcome, didn’t know the consequences. He always did.
So after paving his road to hell with his latest act, he retreated from his brother’s family – physically, at least. He always looked in on them, searched ahead. Saw that Shanna’s inevitable conversation with Dustin went well, and that Isabelle finally fell pregnant and would carry to term. He saw the cousins growing up, their close bond iron-tight with their secret but strained with the toll.
He visited them all to make sure they knew what they were, but for the most part kept to himself. He had made some mistakes with his own child, and he’d make many more, but at least he was here for it. At least he could be here for it.
Hard to take off the white knight’s armour when there were so many suffering, but he’d give enough in the future. He had to try and be okay with that, even if he never really was.
But he set his watch when he left Shanna’s house. Nine years. In nine years time, he had to start preparations.
