The clown seemed disinclined to obey. He threw himself off Yarrow's lap and hid elaborately behind the man's chair. Biggles' eyes peeped over Yarrow's right shoulder, the miniature head peeped over his left. Yarrow turned and swatted at the clown prissily, as if it were a spider he was loath to touch but anxious to kill. Jackson produced his wand--a twelve-inch length of hickory--from his sleeve and pointed it carefully at the clown's empty frame. "Shall I alter your environment while you are away, Mr. Biggles? You'll need to return to it eventually. Would you prefer to find it stocked with a few more Japanese Thorn Thickets?"

The clown frowned petulantly under its make-up and stood. Sulking, it clambered out of Yarrow's portrait and back into its own frame.

        "A simple rule of thumb," Jackson said, watching the clown give him a very enthusiastic nasty look. "A one-dimensional personality can merge into a two-dimensional personality's environment, but not the other way around. Portraits are confined to their own frames, while imaginary subjects can move freely into and through any other painting in their general vicinity. Does that answer your question, Mr. Potter?"

        "Yes, sir," James answered, then rushed on. "One more thing, though. Can a portrait ever appear in more than one of its frames at once?"

        Jackson smiled at James while simultaneously furrowing his brow. "Your inquisitiveness on the subject knows no bounds, it seems, Mr. Potter. As a matter of fact, that is possible, although it is a rarity. For great wizards, whose portraits have been duplicated many times, there has been known to be some division of the personality, allowing the subject to appear in multiple frames at once. Such is the case with your Albus Dumbledore, as you might guess. This phenomenon is very difficult to measure and, of course, depends entirely on the skill of the witch or wizard whose likeness appears in the portrait. Is that all, Mr. Potter?"

        "Professor Jackson, sir?" a different voice asked. James turned to see Philia Goyle near the back, her hand raised.

        "Yes, Miss Goyle," Jackson said, sighing.

        "If I understand correctly, the portrait knows everything that the subject knew, yes?"

        "I believe that is apparent, Miss Goyle. The painting reflects the personality, knowledge, and experiences of the subject. No more and no less."

        "Does a portrait, then, make its subject immortal?" Philia asked. Her face, as always, was stoic and impassive.

        "I am afraid you are confusing what appears to be with what is, Miss Goyle," Jackson said, eyeing Philia closely, "and that is a dreadful mistake for a witch to make. Much of magic, and much of life in general, I might add, is concerned primarily with illusion. The ability to separate illusion from reality is one of the fundamental basics of technomancy. No, a portrait is merely a representation of the once-living subject, no more alive than your own shadow where it falls on the ground. It can in no way be thought to prolong the life of the deceased subject. Despite all appearances, a wizard portrait is still merely paint on canvas."

        As Jackson finished speaking, he turned toward the painting of Mr. Biggles. With one swift movement, he pointed his wand at the painting, not even quite looking at it. A jet of clear, yellowish liquid spurted from the end of the wand and splashed on the canvas. Instantly, it dissolved the paint. Mr. Biggles stopped moving as his image blurred, then ran freely down the canvas. The unmistakable smell of turpentine filled the room. The class was deadly quiet.

        Professor Jackson walked slowly behind his desk. "I fancied myself a bit of an artist when I was younger," he said, studying the end of his wand as he turned. "Mr. Biggles, horrid as he was, was one of my better works. You may freely guess what kind of life circumstances could lead to my creating such a thing, as I myself have forgotten. I thought Mr. Biggles was long forgotten as well, until I found him in the bottom of a trunk while packing for my journey. I thought," he said, glancing over at the streaky mess that ran out of the frame and dripped to the floor, "that this would be a fitting end for him."

        Jackson sat down at his desk, carefully laying his wand on the blotter in front of him. "And now, class, what technomancic truth can we derive from what I've just illustrated?"

        No one moved. Then a hand raised slowly.

        Jackson inclined his head. "Mr. Murdock?"

        Murdock cleared his throat. "Don't try to be an artist if you're supposed to be a Technomancy teacher, sir?"

        "That wasn't quite what I had in mind, Mr. Murdock, but that is inarguably true as well. No, the truth I was illustrating is that, while a wizard painting, portrait or otherwise, is indeed still merely paint on canvas," Jackson's gaze searched the class, then settled on James, "only the original artist can destroy his painting. No one or nothing else. The canvas can be slashed, the frame destroyed, the bindings cut, but the painting will endure. It will continue to represent its subject, no matter what happens to it, even in a hundred pieces. Only the original artist can destroy that connection, and once he does, it is destroyed forever."

        As the class was dismissed, James couldn't help slowing as he passed the destroyed painting of Mr. Biggles. The clown's face was nothing more than a muddy grey blur in the center of the canvas. Squiggly streaks of paint ran over the bottom edge of the frame, puddled in the chalk tray, and dripped onto the floor, making a drab spatter of white and bloody red. James shuddered, and then walked on. He thought he'd never look at another wizard painting the same way again. As he made his way to his next class, he passed a painting of several wizards gathered around a gigantic globe. Ironically, James noticed that one of the wizards, a severe man with a black mustache and glasses, was watching him closely. James stopped and leaned in. The wizard's stare became stonier, his eyes piercing.

        "You've got nothing to worry about," James said quietly. "I don't even know how to draw. Art is Zane's department."

The painted wizard grimaced at him, annoyed, as if James had entirely missed the point. He made a harrumphing noise and pointed in the direction James had been walking, as if to say move along, nothing to see here.

        James resumed his walk to Charms class, musing idly about the wizard in the painting. He'd looked familiar, but James couldn't quite place him. By the time he entered Professor Flitwick's classroom, James had already forgotten the little painted wizard and his piercing stare.

        The day of the much ballyhooed first school debate came and James was surprised at how many people were planning to attend. He had assumed debates were typically stodgy little affairs attended only by the teams themselves, some teachers, and a handful of the more academically-minded students. By lunch that Friday, though, the debate had generated the sort of boisterous tension that accompanied certain Quidditch matches. The one thing that seemed to be missing, however, was the joking taunts between the supporters. Thanks to the carefully worded banners and signs advertising the debate, the student population had been rather evenly divided between two worldviews that, it seemed, were not compatible on any level. The result was a sullen tension that filled the silences where jests and competitive taunts might otherwise have been. James had not been seriously considering attending the debate. Now, though, he realized that the outcome of the event would very likely affect the entire culture of Hogwarts. For that reason, he felt an obligation to go, as well as a growing curiosity. Besides, if Zane was going to be arguing in front of a large portion of the school populace, partly in defense of Harry Potter, James knew it'd be important that he be there to show his support.
