A blond-haired, blue-eyed man wearing a tan trench coat over a white shirt, a tie, black pants, and shoes was standing in front of a house in Privet Drive; Little Whinging, Surrey, England, Great Britain. It was one place; he rather not be at all especially with the person who lives in Privet Drive. His only living cousin beside her nephew and the reason why he's here instead of some bar. This man is John Constantine, the cousin of Petunia Cruella Dursley nee Evans and the late Lily Jasmine Potter nee Evans. Now for the reason, he's here is because of Lily's letter and because of Lily's child Harry James Potter.

When he had first received the letter, he was at his mansion in Liverpool instead of over at the House of Mystery in America. The reason he was there he was meeting Cheryl his sister who he thought was dead, but it turns out she had gotten married to a wizard in Lily's world. He was meeting his niece for the first time. When he had read Lily's letter, he knew he would be too late and so, he went straight to here or rather he had asked Zatanna to meet him here with someone from that world who also was involved with the law.

John walked up the house number 4 but stopped near the doorstep as there was a child who has Lily's bright green eyes. He picked him up and notice the letter with him.

"Ah, you got him good." The voice of Zatanna Zatara said, from behind him

John turned around to see Zatanna and a redhaired woman wearing a longer coat than him.

"Zatanna and you are?" John greeted and then asked the other woman who raised an eyebrow at him

"Madam Amelia Susan Bones, head of the Department of Magical Law Enforcement. Mr. Constantine" the woman Amelia said, and John just smirk at her

"Alright John, Amelia we need to go to Gringotts Wizarding Bank," Zatanna said to both John and Amelia, that's when John finally notices

"Who are you holding, love?" John asks as he walks to his car with little Harry

"This John Constantine is your son, remember Marlene McKinnon?" Zatanna said/asked as she got in the back with both boys

"No," John said as he started up the car and followed Amelia's directions to the places that will help then get to the bank.

But the truth is that he does indeed remember Marlene McKinnon when he had met Marlene, she had helped him solve a case. She reminded him of Zatanna and that was partly why he loved her. But of course, he didn't say that to her face even when she did. In the end, two hearts were broken, but in his cursed life, he didn't need any attachments. So, why the hell did he decided to follow Lily's last wish for him to raise Harry and now he finds out he and Marlene had a son together? Bloody hell

"We're here, Mr. Constantine stop the car." The voice of Amelia Bones snapped him out of his thoughts

He parks the car and looked at the building that Amelia was pointing to, which appears to be a broken-down old shop. But John knew that this was the Leaky Cauldron. He got out of the car with both Amelia and Zatanna doing the same. Amelia had to close Zatanna's door as Zatanna have both boys in her hands. Zatanna gave Harry back to John as she and Amelia both led John into the Leaky Cauldron.

"Are the Goblins still in the bank?" John asks Zatanna as they walked toward the secret entrance to Diagon Alley

"I had a meeting with them, before going to Privet Drive with Amelia" Zatanna answered as she, Amelia, and John walked through.

They continued to walk through Diagon Alley and toward Gringotts Wizarding Bank; John looks around the Alley and notices that some people are still awake and looking at them from their windows. When they were at the bank, they entered and were met with the Potter's family vaults manager Mary Macdonald. Mary Macdonald was a friend of Lily's who was targeted by a Pureblood wizard with the surname Mulciber, just because she was a muggle-born. John was pulled from his thoughts when he heard Zatanna talking to someone that when he notices that they're at Gringotts and Zatanna was talking to a Goblin. After some arguing, Mary Macdonald appears and told them to follow her.

They walked to an office and entered it, inside were three chairs one for each of them. John sat in one near where Zatanna was sitting, Amelia was sitting in the other chair that was near Mary's desk.

"Now Miss. Zatara, I see we have Mr. Constantine here and will young Mr. Potter too. Miss. Bones, why are you here?" the Mary asks

"I'm here to make sure this is legal and true. Can you show me proof that Mr. Constantine is the late Mrs. Potter's cousin?" Amelia asks and all the Mary did was point her wand at a piece of parchment, which held words that now appearing in the air.

"What the bloody hell, how did you get my damn blood? Who the bloody hell is Lily Moon?" John asks and all three women glared at him

"I was the one who took your blood remember, I'm the one who gave it to Mary. Also, Lily Moon is Petunia's daughter who she gave up for reasons I didn't know at that time. The Moon family is a wizarding family, Lily must be a muggle-born witch to be adopted by them." Zatanna told John coldly

"Mr. Constantine, please refrain from cursing enough of children. Thank you, now is that proof enough for you Madam Bones?" Mary said to John, before asking Amelia

"Yes" Amelia simply said to Mary's question

"Good, now Mr. Constantine if you still have your letter from the late Mrs. Potter, please give it to Madam Bones. So, she will get some new information about Lord Black, and yes Madam Bones, he's still Lord Black as he never was convicted of anything." Mary said to John and Amelia

John dug into his coat's pocket and pulled out his letter from Lily and gave it to Amelia who unfolded it to read it. John watches as Amelia's face has a hint of anger from reading it, so she must be on the part where Lily talked about secret keepers and that Peter Pettigrew as their secret keeper. After Amelia finishes, she looks up at John.

"Mr. Constantine, I would like to borrow this for a while. Do I have your permission?" Amelia said/asked

"Go right ahead, love," John said as he lifted Harry some more

"Good, now that's settle. Mr. Constantine, there are other matters we mush discuss. Madam Bones, it's best that you stay for this and Zatanna I do believe Lord Moon is in the bank as well meeting with his manager. Here's a copy of this" Mary said as she handed Zatanna a copy of John's heritage.

John watches as Zatanna stood up, take the copy parchment, and left the office. John turned back around to face Mary as Amelia did the same. Mary told that when Zatanna had come to her about John and Lily's letter, she did some digging into Potter's vaults account. She found that several things that are worriment, one someone been taken money from the vaults and this someone had a key. The second time that it's happened many books and heirlooms had been taken; Mary did discover that this person was Albus Dumbledore who had also given some to Severus Snape.

Meanwhile, Zatanna Zatara was walking through the bank to find Lord Moon, when she found him just leaving.

"Lord Moon" Zatanna called out, causing him to stop and turned around to face her

"Yes?" Lord Moon asks Zatanna from where he was standing

"I'm Zatanna Zatara, I'm here with John Constantine who here to take custody of Harry James Potter. We did a heritage test on John to make sure that he is related through the late Mrs. Potter and- "Zatanna was saying until she was interrupted

"And you saw my daughter Lily's name next to Petunia Dursley's name?" Lord Moon asked, already knowing what this is about

"Yes, but I'm very sure that John doesn't want to take Lily from you. We just want to know if she's a Muggle-born as her biological mother is Petunia. We also- "Zatanna was once again interrupted

"There's a tea shop that's open at night as the owner doesn't sleep or rather refuses to until her grandchildren force her in the mornings. We'll talk there" Lord Moon said as he and Zatanna walk out the bank and toward the shop

When they were there, Lord Moon and Zatanna sat at a table together. Lord Moon ordered for them both. When their order arrived, Zatanna looked at Lord Moon ready for what he has to say, or she thought she was.

"Lily is the daughter of Petunia Dursley, but Vernon Dursley isn't the father. Lily's father is Arthur Weasley and so, she's a half-blood." Lord Moon said, much to the shock of Zatanna

"What? How? Does Arthur Weasley know?" Zatanna asks, but Lord Moon shook his head

"No, but as for the question of how. One of Mrs. Dursley's friends is a squib, although she never told Mrs. Dursley this. She had seen people under love potions before and so, knew that Petunia and her love affair boyfriend Arthur were under some love potions. She found a way to contact Mrs. Potter, Mrs. Potter was able to cure Lord Weasley. Unfortunately, she couldn't get close to her sister until Lily was born. Somehow these kinds of love potions also erased memories, which is why Lord Weasley doesn't remember; but Mrs. Potter knew her sister wouldn't take care of a magical child and gave her to us." Lord Moon explained

Zatanna can't make sense of any of this, but she knows one thing she needs to tell John whether he wants to hear it or not.
