"Oh, you are a surly little bastard this early in the morning, aren't you?" Marcus laughed. He leaned over the desk, picking up his cigarette case, not willing to take a bunch of snot from someone who was little more than an overpowered schoolboy. Marcus had run out of any sort of diplomacy from Krum's first mouthful of arrogance. If Krum wanted to die, what business was it of Marcus's? Much as he cared for Stelladora, Krum deserved to have at it, if he was that self assured. Most of Marcus's private security assignments had been puffed up aristocrats, but that didn't mean that Marcus had to like them any more. And he didn't. Marcus's sarcasm was not liable to fail him, and in fact, it was liable to be quite thick. He knew he could censor himself, but he honestly didn't feel like it. When it came to arrogance, Belby could lay that on equally as thick whether he meant it or not, and when it came to pairing arrogance and sincerity and making it work--that was an odd oxymornic crap shoot.
"Now, listen, Boy," Marcus's words were pointed, each one deliberate. "I am not a diplomat, nor do I pretend to be. So since you feel I am a waste of your time, I won't bother with diplomatic civilities and cut straight to the chase. I do not have to like you, and you do not have to like me. In point of fact, much as I am fond of Stella, I am not overly fond of most of you Krums. Your father is a huge arse, and your mother was even worse, but somehow that apparently didn't keep you from being a self centered little buggar yourself.
"I do not particularly need an invitation from you or your minister to be here. I work for the Bulgarian Ministry of Magic, and international law permits me to be here. You're welcome to check both the law itself and my passport to double check me, but I doubt you have the energy. I am here as a favor to Stelladora. And I don't particularly feel like giving you my resume since you have more skills than anyone else in England, obviously." Marcus knew he could also have produced his identification from the Bulgarian ministry, but it was a waste of time and energy in this office.
"You should understand a couple of things. First, you do have a number of people right here under your nose who would love nothing better than to hoist your head on a pike. Yours and your minister's. And judging by your school transcripts, you probably aren't amongst the top scorers here in auror skills, so you might want to brush up on your Defense Against the Dark Arts if you want to stay alive or keep all your offspring breathing. And, yes, I did do my homework. I did pull your grades and just about everything else in your dossiers--yours, Minister Lupin's, and his daughter's. Its my job. My lovely ex thought you might care a tad bit about whether you and the woman lived, but I'm betting she got the whole thing dead wrong. I'm betting you don't give a flying fig about your boss, and so be it.
"You obviously think I'm an egotistical prick, and I am. You got that much right. I do what I do because I'm good at it. Why else would Stelladora have even bothered with me after all these years? She knows I wouldn't have an ounce of patience with you. And surely she knows you wouldn't be amused either.
"But since you have all the answers, you just go right ahead and have yourself a happy little rebellion, and do try to survive the warm little cell in Azkaban they surely will have planned for you. Because if I were them? That's exactly what I'd do. Unless, of course, they plan to simply move to assasination and get it overwith. But given the skill levels in your file, you might have a bit of a squeeze fighting yourself out of it without help." He turned and headed to the door and then turned back.
"Oh,and two more things? If Miss Finnegan chooses to not add milk and sugar to her coffee, then surely she knows how to make it correctly. That's to her credit. And secondly, when you do find your Defense Against the Dark Arts texts again, you might want to read your basic magic primer as well. Look under 'Howler.' I believe you will that it isn't entirely harmless if you choose not to read it. Do at least spare Miss Finnegan from having to deal with your dangerous paperwork. She doesn't deserve that."
Marcus had a back up plan of his own--one he hadn't shared with Stelladora. She didn't need to know. If Krum could not be trusted, Marcus did owe something to, not only the Ministry he worked for, but also to the one from his homeland.
