Over the few days between sending the letter to Sirius and them going, Alexander and Hermione had been relaxing as much as possible. They still exercised and trained, not able to simply sit around, and they had started reading through the texts that Severus had found for them about Animagus transformation, making them swear to not try anything without him being present. It had been interesting on Monday, the day before they were to meet Sirius, when Nye had trotted into the Great Hall during breakfast. He had been bored and chased a rabbit in, not realising what he was doing. Severus was the only one who truly knew about the Golden Pegasus, so the demigods had gone through the whole story over how they saved him, during the retelling Nye had basked in being the center of attention and preened even more when he heard Grubbly-Plank request to use him in her class.

Early on the Tuesday, Hermione and Alexander woke, it was still dark but they still did their usual routine, going a few extra miles to completely warm themselves up. Shower and dressing, they ate a hearty breakfast with the staff before heading off. They took the Floo to Lex's home, before jogging to the nearby park and just waited.

"We really should have put down a time," Hermione sighed as they entered their third hour.

"He's a dog Mia, how's he going to tell time exactly?" Lex spied the swings just off from them, and pulled her towards them, "Come on, you still have to beat me."

"It's not fair though, you use air to go further than me," the witch pouted over her smile as she sat on one of the swings.

"I won't this time, promise," of course, he had his fingers crossed when he said that.

The teens pushed off, going higher and higher, their laughter flying through the air with them. Finally they were at the height needed, and with large breaths, they jumped off. With their extra training over the years since their last go at it, their landing was softer but they also were able to go farther. And once again, Lex used the air to push him just that much farther to beat his girlfriend.

"ALEXANDER!" Hermione screamed unhappily, tackling him to the ground and pinning him beneath her, "You will pay for that."

The wizard smiled, and reached up to push a lock of hair back behind her ear, "Yeah but you're really beautiful when you're like this."

Blushing lightly, the witch leaned down, placing her lips against his softly. As soon as her boyfriend was deeply into the kiss though, the witch threw a water ball into his face, "Payback."

Lex groaned but simply rolled so that he was on top, going back into the kiss he had been pulled from rudely. They were still like that when they felt the extra presence, so looked up to see a large black dog grinning down at them, "Padfoot I presume?"

The dog looked around before changing into a man. This man was as thin as a rail, his hair long and unkempt, his beard was awful, he smelt as though he hadn't bathed in years, and his eyes were deep pits. But when he looked at the entwined pair, who were now on their feet, his mouth curled into a warm smile, "Just like James you are."

"Nice to know," Lex said softly, "Come on, change back and follow us."

The man did as told, following them as they returned to Lex's home. Once inside, Sirius returned, and looked about, "Whose place is this?"

"I live here during the holidays but before we explain anything, you need to go up those stairs and shower. No offense but we won't say one thing to you until you are spotlessly clean. There's a razor, and we will find some clothes that will fit you," Hermione ordered sternly before smiling, "You will be told everything."

The thought of an actual shower had the man racing up the stairs, followed calmly by the demigods who found him clothes from Severus' dressers, and a towel. Whilst he cleaned up, they set to making a large meal, certain he hadn't eaten anything in a while. After an hour, the man who came down the stairs looked much more human. His beard and hair were now trimmed, and the many layers of grime were removed. His eyes grew at the sight of all the food and he dove in eagerly.

"My apologies, I haven't eaten this well since before prison," Sirius said between bites, "I can eat and listen."

"Right, so there is so much we have to tell you, some that we've only told a few people, but first of all we need you to know that if you even think of insulting one Severus Snape, we will beat you over the head with your bloody arms. Understood?"

Seeing the ferocity in their eyes kept Sirius from saying anything other than, "Ok."

"Good. Now this is the house that Severus and I live in during the summers, or at least we did last summer when he bought it and probably will be next summer too," Lex shook his head before pointing out the back, "Connected to the yard is another yard and house, that is where Hermione and her adoptive parents live. I see them both as my own adopted parents also, so if you are to hear me talking to them and I call them Mum and Dad, don't be concerned; they've looked after me since I was 6.

"The biggest thing, and I would think the hardest for both you and Remus Lupin when we tell him, is that I am not the real Harry Potter. Well, I sort of am but also not. See the Potters' son died through a third trimester miscarriage; they told no one about it except for Severus as he was there when it occurred. It was helpful though when 6 months later, Severus was in need of a family to place me. I was 6 months old, and had been kidnapped with Hermione by someone on Voldemort's orders," Lex saw the shudder and thought that the man was going to break at the strength of it, "Anyway, Severus saved us, placed Mia with the Grangers and me with the Potters. I am the same boy who you were made godfather over, the same one you knew as Harry, only I'm not biologically a Potter."

Sirius had stopped eating as soon as he heard the boy say he wasn't really Harry, "But why would Snape do that? And you look so much like them both."

"Appearance wise, it is nothing but a fluke, though it did earn me more than enough beatings during my sentence with the Dursleys, who have been dealt with. As for why he would do it, answer me this question, did my parents, the Potters, look like they were happy with me?"

"You were their everything, I mean, I survived in Azkaban on the memories I have with you three. I get why he did it. So if you aren't Harry, who are you?"

The wizard took a deep breath, squeezed his love's hand, and answered, "We are Alexander Olympius and Hermione Hippia, the son and daughter of Zeus and Poseidon respectively."

Sirius toppled over in a dead faint.
