Many thanks to Andrew Ryser Szymanski for this:
BJ: "I'm sorry Dom, but you know I've got no alternative. This is going to bring the whole administration down. I'm afraid I've got to let you go".
DC: "No you haven't fat boy. You know I've got the full file on you. Everything. The lot. Do you think I didn't know this moment wouldn't come one day? Just call it little me taking precautions".
BJ: "You wouldn't. Surely you couldn't sink that low. I'll deny everything. That's bloody treason".
DC: "Your choice, fat boy. Less than 6 months from hero to zero, my little Churchill.
BJ: "But you just can't. I'll deny everything".
DC: "I've got it all fatboy. Photographs, emails, corroborating statements. You're toast fat boy".
BJ: "Look Dom. Be sensible. We can spin this. I'll make a public address. Greatest regret at losing you and all that, doctor's orders, ongoing condition post Covid forcing your brave resignation. Heroic service re Brexit, possible knighthood. How's that?"
DC: "Do you want to see these emails and photos"?
BJ: "OK, OK, I'll tell 'em you did nothing wrong and have my total support. I'll tell Baker and anyone else making trouble that they're finished. I'll do that today. You the boss, Dom, baby".
DC: "Excellent Prime Minister. A man just has to know his limitations".
