'So far it makes sense, then. But why – an intelligent horse might ask – why was John Churchill also in Brussels – part of Spain's, and therefore the Pope's, dominions? Why, it's because – thanks to the maneuverings of his daddy Winston – ever since John had been just a lad, he'd been in the household of James, King Chuck's brother, the Duke of York. And York – then, and now, first in line for the throne – was, and is today – you'll like this – a fanatical Papist! Now do you understand why London was, and probably still is, nervous? The King decided it'd be better if his brother took a long vacation out of the country, and naturally James chose the Catholic city that was closest at hand: Brussels! And John Churchill, being in his household, was obliged to follow him, at least part of the time.
