Harry stopped by a window. "And once they've achieved their goal of total disclosure with the Muggle world?"

        "Well, there's only one outcome to that, isn't there?" Franklyn answered.

        Harry's face was thoughtful in the moonlight. "Muggles and wizards would descend into competitions and jealousies, just like they did in eons past. The dark wizards would make sure of it. It would start as small challenges and outbursts. Laws would be passed, enforcing equal treatment, but those laws would become the basis for new contentions. Wizards would demand to be placed into Muggle power structures, all in the name of 'equality'. Once there, they'd push for greater control, more power. They'd win over Muggle leaders, using promises and lies where they could, threats and the Imperius Curse where they couldn't. Eventually, order would break down. Finally, inevitably, there would be all-out war." Harry's voice had gone soft, considering. He turned to Franklyn, who stood watching him, his face calm but dreadful. "And that's what they want, isn't it? War with the Muggle world."

        "That's what they've always wanted," Franklyn agreed. "The struggle never stops. It just has different chapters."

        "Who's involved?" Harry asked simply.

        Franklyn sighed again, hugely, and rubbed his eyes. "It's not so simple. It's virtually impossible to tell the instigators from their followers. There are some individuals it would be instructive to watch closely, though."

        "Madame Delacroix."

        Franklyn glanced up, studying Harry's face. He nodded. "And Professor Jackson."

        James gasped, and then clapped his hand over his mouth. His dad and Professor Franklyn stood very still. James was sure they'd heard him. Then Harry spoke again.

        "Anyone else?"

        Franklyn shook his head slowly. "Of course. But then you'd just be watching everyone and everything. It's like an infestation of cockroaches in the walls. You can either watch the cracks or burn down the house. Take your pick."

        James backed away very carefully, then when he felt safely out of earshot, he turned and retraced his steps back to the Americans' quarters. His heart was pounding so heavily he had been sure that his dad or Professor Franklyn would hear it.

        He knew the so-called Progressive Element was no good, but now he knew it must be them that were planning the return of Merlinus Ambrosius, believing he would help them to accomplish their false goal of equality, which would lead inevitably to war. Merlin had said that he would return when the balance between Muggles and wizards was 'ripe for his ministrations'. What else could that mean? He hadn't been surprised that Madame Delacroix might be involved in such a plot. But Professor Jackson? James had come to quite like the professor, despite his crusty exterior. He could hardly imagine that Jackson could be secretly plotting the domination of the Muggle world. Franklyn had to be wrong about him.

James ran lightly past the Americans' quarters, looking for the door to the guest room he and his dad were staying in. With a sudden stab of fear, he remembered that the doorway had vanished when he'd come out. It was a magical room, after all. How was he supposed to get back in? He had to be inside the room, apparently asleep, by the time his dad came back. He stopped in the corridor, not even sure what stretch of wall the doorway had appeared in. He glanced around hopelessly, unable to keep himself from looking for some subtle clue or hint of where the doorway was hidden. What had his dad called it? The 'Room of Requirement'? James had remembered his wand this time. He pulled it out and shook his hand out from under the cloak, revealing it.

        "Uh," he began, whispering harshly and pointing his wand at the wall. "Room of Requirement… open?"

        Nothing happened, of course. And then James heard a noise. His senses had grown almost painfully sharp as his body shot full of adrenaline. He listened, his eyes wide. Voices. Franklyn and his dad were coming back already. They must have begun their return journey at almost exactly the same time as James, but a little slower. He heard them talking in hushed voices, probably as they stood by the door into Franklyn's rooms. His dad would be returning in mere moments.

        James thought furiously. What had his dad done to open the room? He had just stood there, hadn't he, waiting, and then bang, there was the door? No, James recalled, he had spoken first. And paced a bit. James replayed the evening in his memory, trying to remember what his dad had said, but he was too flustered.

        Light bloomed at the end of the corridor. Footsteps approached. James looked down the corridor frantically. His dad was approaching, wand lit but held low, his head down. James remembered that he had his own wand held out, his arm outside the cloak. He yanked it in as quickly and silently as he could, arranging the cloak to cover him completely. It was hopeless. His dad would enter the room and see that James wasn't there. Maybe James could follow him in and claim to have been to his rooms to get a book he needed? He had never been any good at lying. Besides, he'd have the cloak with him. He almost groaned out loud.

        Harry Potter stopped in the corridor. He held the wand up and looked at the wall. "I need to get into the room my son is sleeping in," he said conversationally. Nothing happened. Harry didn't seem surprised.

        "Hmm," he said, apparently to himself. "I wonder why the door won't open. I suppose…," he looked around raising his eyebrows and smiling very slightly, "it's because my son isn't sleeping in the Room of Requirement at all, but is standing here in the corridor with me, under my Invisibility Cloak, trying as hard as he can to remember how in the world to open the door. Right, James?"

        James let out his breath and yanked the Invisibility Cloak off. "You knew all along, didn't you?"

"I assumed it when I heard you gasp downstairs. I didn't know for sure until the trick with the door. Come on, let's get inside." Harry Potter chuckled tiredly. He paced three times and spoke the words that opened the Room of Requirement and they went in.

        When they were both in their beds, James in the top bunk, staring up at the dark ceiling, Harry spoke.

        "You don't have to follow in my footsteps, James. I hope you know that."

        James worked his jaw, not ready to respond to that. He listened and waited.

        "You were down there tonight, so you heard Professor Franklyn," Harry finally said. "There's one part of what he said that I want you to remember. There are always plots and revolutions in the works. The battle is always the same, just with different chapters. It isn't your job to save the world, son. Even if you do, it'll just go and get itself into danger again, and again, and again. It's the nature of things."
