Thomas Wintour looks quizzical.
Wintour: “A guy? What? Is that like a jakes or something? ..Did you put a bomb in the privy.”
More explained in the next page. But yeah “Jakes” or “jake” is still used as Irish slang, but most people would know it as the corruption the “john”. Privy is old enough slang to use in this situation, but loo isn’t. I’ll make sure to be anachronistic on other pages but I’ve gotta have my toilet humour.
