*it turns out the saleswizard has managed to locate five of the six editions Sirius wants, which means that when he gets back home (if he gets back home) he'll have nine editions neatly lined up with a space where the tenth (the third, actually, if you're speaking chronologically) is missing, and which is going to annoy him for the rest of the month because while he's not obsessive compulsive (no, of course not, and don't believe anything Remus or James tells you [and in fact, ask Regulus, who is even more obsessive compulsive than Sirius {or would be, if Sirius were obsessive compulsive, which he isn't}]) things that are missing or incomplete cause him something close to actual, physical pain, even though the 1986 edition is among the five that have been located* *but then it's entirely possible that the next time he comes to London, he'll be in a completely new reality all together, and the elusive third edition of "Healthening and Replenishment -- Compendium" may turn up after all* *is about to laugh at this ridiculous proposition when the sales wizard gives him a nervous look, and he remembers himself enough to hand back the coffee things, pick up the books, and wander back to the front counter, where he waits for the attendant's attention*
