Sunday dawned so early for Harry that he was able to get a note penned and on a school owl in plenty of time to return to the Gryffindor common room and poach a third year Runes text. He'd decided, eventually, that just hoping that people would leave their books out forever was rather ridiculous, so he'd been trying to create a library under the giant red-orange couch.
Of course, that lasted until about mid-day, when Percy Weasley summoned his lost Arithmancy book with an Accio. Hm, Harry thought, I'm going to have to do a better job... Of course, by midday, Harry'd been playing exploding snap with Ron. Ron still wanted to talk about the three headed dog, but Harry really didn't have good memories of dogs.
Or adventures, for that matter.
Of course, Harry had to remind himself that he was a Gryffindor, so he was expected to do these things. He, well reminded, laid into them with fervor. As if it would be easy for a few first years to defeat something that outweighed them by about five times.
That night, Harry met with Zambini, quickly outlining the plan in a deserted coatroom right off the main entrance. "What do you want for your help?" Harry asked. Zambini stuck his hands in his pockets, affecting nonchalance, "Haven't thought it through properly yet." He said, "So, let's do this the Slytherin way."
"What's that?" Harry asked guardedly.
"We'll cast the Iuncturam, and then when the deal's been properly concluded, we'll sever it." Zambini says.
"What does it do, really?" Harry asked.
Zambini responds, "Nothing, really. It's just a way of formally sealing it."
"Can you have more than one at once?" Harry queried
"Loads. I don't think there's any limit." Zambini said, "there is another spell for revealing whether a person has debts, or whether two people have a shared debt."
Harry nodded firmly, "sounds fair. Time's burning, let's be away."
Zambini and Harry cast the spells, the binding glowing green as they clasped each other's biceps
