She had not, of course.
At first, James had believed that this was because Petra was still in love with her former beau, Ted Lupin. Later, however, he'd realized that Petra had been under the influence of a secret, awful curse. Due to a series of very wicked schemes, set in motion by none other than the long dead Dark Lord himself, Petra Morganstern was the living carrier of that villain's last, ghostly shred of soul. It had been imparted to her while she was still in her mother's womb, transmitted via a special, nearly unheard-of bit of cruel, dark magic: a special kind of Horcrux, in the shape of an ugly silver dagger.
James' dad had done some research on it, with the help of Aunt Hermione, and had discovered that such a thing was called a 'transcendent Horcrux'. They'd only found one reference to it, in a book so dark and treacherous that James' dad and Uncle Ron had had to bolt it to the table with silver stakes to keep it from snapping their hands off. According to their awed, whispered conversations (which James and Albus had surreptitiously listened in on), a transcendent Horcrux was purely theoretical; no one, at the time of the book's writing, had ever succeeded in actually creating one. Unlike other Horcruxes, a transcendent Horcrux could never be used to restore the bit of soul it contained to its original host. If such a thing were attempted, it would act as a kind of poison, killing every other bit of the soul it had been sheared from, regardless of how many normal Horcruxes were in use. The shred of preserved soul in a transcendent Horcrux had to be passed on to another host, accepted willingly, there to spread its influence and live on, leech-like.
Petra's mother had been tricked into transmuting the curse of Voldemort's soul into her unborn baby, but that didn't make James hate her any less. As far as he was concerned, the woman had to have been either stupid, gullible, or blind. Miraculously, however, Petra herself loved her long dead mother, loved her and missed her enough to have nearly doomed all of mankind in the hopes of somehow bringing her back to life. In the end, fortunately, Petra herself had been stronger and smarter than her mother had been, and she had made the right choice—the hard choice. She had rejected the deal offered to her by the otherworldly beast called the Gatekeeper, even though it had meant the loss of the one thing she'd most wanted in all the world: the return of her dead parents.
Not very surprisingly, the realization of all of these things had not in the least diminished James' fascination with the young witch. If anything, it had increased it. James himself had confronted the Gatekeeper, and knew the awful stresses Petra had to have endured in rejecting its tantalizing offer. Furthermore, there was just something about Petra, something about the reality of her internal struggles and her painful, personal losses, that made James want to be brave for her.
In his most secret heart, she awoke a deep, pervasive sense of manly nobility. He wanted to defend her, to slay her dragons, to be her knightly savior. Of course, he told no one about these feelings. He was sheepish about admitting them even to himself. In the light of day, his infatuation with her seemed silly, childish, quaintly preposterous. She was of age, for one thing, graduated and free, a young woman moving out into a grownup's world, while he was still a month shy of fourteen. Still, the feelings clung to him, as did his affection for her. Without even trying, she had smitten him. Fortunately, as the summer had progressed, absence and distance had helped James begin to forget the girl who had occupied so much of his attention during the previous school year. Such, he thought (rather wisely for his age), was the nature of young love.
And then, to his mingled dismay and delight, Petra and Izzy had arrived at the Potter family home, escorted by Ted Lupin, Damien Damascus, and Sabrina Hildegard. There had been much curiosity about what had brought them there, but very few questions, at least at first. It was apparent that something awful had happened, something that had resulted in the deaths of both Petra's grandfather and his horrible wife, Phyllis, Izzy's mother. Ted, Damien, and Sabrina had kept quiet about whatever they had seen at Morganstern Farm, apparently believing it was Petra's tale to tell (and later because Merlin had apparently sworn them to secrecy). Ted had, however, taken James' dad and mum aside and asked if it would be all right if Petra and Izzy stayed at the Potter home until things settled down. This had been agreed to quickly and with very little fuss, so that by that very evening, James had found himself going to bed only one wall removed from the girl who, completely and inexplicably, commanded his every affection.
He'd lain awake that night and listened to the soft footsteps and murmured voices in the next room, wondering what it all meant, if anything; wondering if there was something he could do, some way to salvage the bravery he'd felt only days before, when he'd told himself that if Petra had been coming back to Hogwarts the next term, he would have told her exactly how he felt about her, and done whatever was necessary to inspire the same in her.
He lay awake now as he had then, staring up at the fresco of the Atlantean warrior wrestling the unfortunate octopus, and wondered much the same things. Petra had accompanied the Potters on their trip across the ocean, apparently intending to seek employment at the school James would be attending during their stay. Considering her intellect and her uncanny magical skills, James thought it very likely that she would get any job she applied for. In short, Petra's life seemed, even now, to be mysteriously intertwined with his own. It was like the play, The Triumvirate, all over again, like their fleeting, staged kiss at the end, the one that should have ended so wonderfully, and had instead ended with chaos and near tragedy. The mingled hope and fear filled James with a queer, intense range of emotions.
And on the heels of that, James was reminded of the odd, creepy words that Professor Trelawney had uttered to him early that very morning. The professor was, of course, a few octocards shy of a full deck. Hardly anyone believed her proclamations and visions. And yet, what James had heard and witnessed in the corridor with her that morning had been dramatically different than anything he'd ever seen in her class. It had seemed all too real, all too certain. But what had any of it meant? James didn't know, but maybe Lucy would. She was smart about such things, remarkably pragmatic and clearheaded. He made a mental note to ask her about it during their voyage.
As James stared up at the fresco over his head, a soft noise caught his attention, coming from the corridor outside his room. A shadow obscured the ceiling fresco for a moment and James glanced down toward the bar of light beneath the heavy door of his room. The unmistakable silhouette of a pair of walking feet passed by. James frowned curiously.
"Hey Al," he whispered. "You awake?"
"Mrmmm," Albus declared from the other side of the narrow room, rolling over.
James considered waking his brother, even got out of his own bed and reached to shake him, but then he thought better of it. Holding his breath, he approached the door, thumbed the latch, and pulled it open as quietly as he could.
There didn't seem to be anyone in the corridor. Lantern light flickered silently, reflecting on the tiled marble floors and white walls. Leaving the door slightly open, James padded along the corridor in the direction that the shadowy figure seemed to have gone. He reached the end of the corridor and entered a larger hallway lined with statuary and doorways on one side and tall crystal windows, interspersed with pillars, on the other.
