As Harry looked at the pictures in his photo album, he had the feeling that something was wrong, something was off, something to do with the pictures from the months leading up to his birth. First of all, there were no images of his real father who had supposedly been close to the Potters before the betrayal. He'd been told by people who had been close enough to the Potters to know that Lily had cheated on James. Sirius Black had said as much when he'd come to retrieve Pettigrew and netted Ron as well. The fact that he was unnaturally young looking for his age, unnaturally intelligent if scatterbrained and more mechanically inclined than magically inclined, seriously allergic to willow bark and anything derived from it, and had two hearts would've been proof enough of the affair even if he hadn't been told.
In his opinion, it was a pity Snape hadn't been aware of the affair, seeing as it wasn't widely publicized and his messy black hair made him look something like James Potter. Things probably would've been easier for him if he had, since Snape hated James with a passion and would've quite likely gotten a kick out of the fact that he'd been cuckolded, even if it meant that yet another man who wasn't him had gotten Lily.
As Harry flipped through the photo album, he never once noticed the fact that in the photographs taken in the month leading up to his birth Lily hadn't looked the least bit pregnant.
Tenza were good at hiding their true natures, even from themselves...
July 29, 1980:
He'd been drifting for ages. That was how it was for the Tenza. They were born in space and remained in hibernation, in near perpetual infancy until they reached a world where there would be someone to raise them as their own. He had made his way to such a world in an egg whose shell was as strong as the hull of a spaceship. A world where the inhabitants were kind and would probably still care for him even if they did know.
His drift slowed as he was caught in orbit around a small blue-green world which was the third planet out from a rather ordinary yellow sun. He went around once, twice, the pleas echoing in his small mind, pleas in a variety of languages, all of which were variants on the theme of "Please God, please just give us a child. One child, that's all we ask.".
He made a decision. Using the psychic powers that were endemic to his species, he sent his egg hurtling to a small island off the coast of Western Europe, though he didn't know it was called such at the time. The shell of his egg protected him from the burning heat of atmospheric entry and absorbed the shock of impact when he landed near the country home of a couple named Harrowgate, cracking open to reveal an unharmed baby Tenza who awaited his new parents for whom he would become the perfect child.
When the Harrowgates who'd rushed outside to see what the matter was touched him, he absorbed their DNA and unconsciously hid the fact that he wasn't theirs from them and himself. The entire process had been instinctive, having been hardwired into his genetic structure, as had the instinct to psychically bond with his parents whom he depended on for survival.
The Harrowgates named him Agustus Alexander.
July 31, 1980:
The Harrowgates were on their way to visit Richard's parents when the cloaked and masked figure who had been riding an honest to goodness broom had flown past the car. Wilhelmina who had been holding Agustus for whom they'd yet to get a carseat despite the fact that they'd had seven months' worth of advanced warning had nearly dropped her son in shock.
Three more such figures appeared and soon harried the car off the road and into a ditch.
With a sound like a pair of gunshots help had arrived, but it was far too late...
The Doctor who had been running towards the sound of screeching tires while Jamie trailed in his wake hurried his pace upon hearing what sounded like gunshots but carried the psychic impression of a rapid opening and closing of the space-time vortex in which the TARDIS traveled. All too soon, he found himself running down an embankment towards an overturned automobile which was merrily blazing away like a bonfire while a red-haired woman struggled to pull a bundle of some sort from it. A short distance away, a young man with messy black hair fought several masked and robed figures who hurled psychic attacks at him, hurling back the same in kind.
With a cry of "Creag an tuirc!" Jamie launched himself into battle, going to the dark-haired man's aid. Quite likely because the masked and cloaked figures looked rather sinister, and that type were usually up to no good in such situations. As Jamie joined the fight, the Doctor made his way down to the burning car from which the red-haired woman who was little more than a girl, younger than Jamie even, had pulled a small whimpering bundle which she cradled in her arms.
Examining the baby who seemed to be dying despite the fact that it appeared miraculously uninjured, he quickly realized what had happened even though something seemed to be fighting him the entire way. Something that kept weakly insisting that the baby that the red-haired girl was holding was an ordinary child, each protest of normalcy growing weaker and fainter than the last.
"It's no use." he said. "He psychically bonded himself to his adoptive parents, and the bond was broken far too soon. The backlash from it is killing him."
The girl who was on the verge of tears looked down at the small brown-haired newborn resolutely, much the way Jamie did when he encountered something he wouldn't stand for.
"I-If, if he could bond himself to someone else..." the girl said hesitantly.
"Even if it could work, there's no time." the Doctor replied, guessing at her plan. "Your husband is still busy fighting, as is Jamie."
Pulling a knife out of her sleeve, the red-haired girl cut open her palm and that of the infant.
"In Magic, Flesh, Blood, and Bone, I adopt you as my own." the girl said as she pressed her bleeding hand against that of the infant. There was a bright flash and both her hand and the baby's were healed.
"Would you let a baby die right in front of you if you could do something to help?" the girl asked as she handed him the knife.
Realizing that the answer to the question was "No", he followed the pattern of the ritual which was apparently meant to psychically tie a new parent to a child and alter its genetics, much the way Tenza did following their arrival on the planet on which they would live. A second later, he pulled the girl away as the baby began to glow with a bright golden light.
"Oh dear" he said as the baby Regenerated.
