Lily Potter was here at the school making sure all the appropriate safety measures were taken by the teachers and aurors. These safety measures included some of the automated magic that would activate if someone attempted to come in besides coming here physically. Unfortunately it only covered Hogwarts itself and not Hogsmeade.
They had just discovered that some of these magical defenses had been altered in such a way that Apparition is possible. After inspecting the work she sighed in relief when she realized this was not his work. This was likely the work of a copycat, not the original. But then the magic lit up while they were inspecting it and they realized that the copycat serial killer was back.
Lily cast a quick spell and tracked it to the Ravenclaw main room. They ran as fast as they could to the room. It caught the attention of many of the students and guests when they saw so many aurors, teachers, and guests running toward the source of the spell. They had left a few aurors and snape behind to watch the magical defense. They would have to be careful about changing it back later.
They moved into the Ravenclaw common room and were just in time to see Harry, her son, and another female student. They were looking around warily with their wands out.
"Harry!" Lily called out and ran forward and hugged him before looking around. "What happened? Where are they?"
Harry blinked in confusion for a moment. Wondering how his mother knew. Then he realized that the reason such a large group of aurors and teachers had arrived was because the serial killer must have set off some sort of signal. The aurors and teachers were already spreading out around the room while looking over the other students that had arrived just ahead of his mother.
"A white robbed man with a metal mask? He was tackled by another student and they turned into this weird foam like substance. It was odd. But it sounded like he wanted to kill us." Harry then thought of something. Harry then pointed at a bookshelf. "There is a dead auror behind that bookshelf and he decided to kill that rat for some reason."
"That is not a rat…" Lily sighed as she flinched. "That is Peter Pettigrew."
The aurors moved over and looked over the two bodies. "This is bad. The description mister Potter just gave sounded like a disciple of that person. Are we looking at a resurgence?" Another of the aurors asked.
"We have to change the amount of security that is here. What about the dementors?" Another auror asked.
Then an older woman, Amelia Bones, spoke up. "We should discuss this in private." She looked over at the various students. "Have the students return to their dorms. Except for the Ravenclaw students. Have them gather in the dining room for tonight." Amelia then looked to Lily, "tell him the truth. Take him to the Headmistress' office. I personally checked the enchantments. Just remember to put the paintings to sleep."
Lily looked horrified for a moment before nodding shamefully. She looked at Harry and grabbed him by the hand. "Come with me Harry." She then began pulling him away while biting her lip. She saw a black dog quietly following them.
"Mother, what is going on?" Harry asked. His words caused her to shiver. His innate power had already progressed so far. She could feel it subtly influencing him to tell him everything at the moment. Whether it was the secrets she was keeping to the diaries she was beginning to have of Harry. Even the fantasies she was having.
"Harry… Please wait until we are there." Lily told him as they quickly walked through the halls. As they did she could hear several whispers coming from the students and teachers.
"Harry bagged another hot woman. Damn she is hot."
"She is a little too forward. Pulling his hand like that."
"What a cougar… that reminds me. I saw Harry feeling up your girl the other day."
"I know. I actually caught them fucking in a classroom. He was really giving it to my girl."
She underestimated Harry's lineage. She never thought he would be far more forward than his father. She never expected that where his father was unknown, him being kept out of the light of others would result in him becoming such an attractive prospect. Or maybe it was because his magic was that much stronger?
Eventually they arrived at the Headmistress office and Lily pulled out her wand. Waving it a few times. The doors loudly locked while all the paintings went quiet and seemed to enter a dormant state just like the ones in the Ravenclaw main room had done.
Harry turned around to see the black dog that was following them turn into the black haired woman that woke him up and bounced on his cock. Her abdomen was slightly distended and when she fully turned human she put a hand on it and smiled at Harry.
Lily rolled her eyes when she realized one of her best friends and secret lover had already pounced on her son and likely used various spells to ensure she was pregnant. She was still dressed in her very revealing black lingerie. It had changed a bit over the years, she updated it as time went on. But she always dressed like this because those were the orders of her 'lover' before he died.
Harry went to ask something when he saw the other woman but shook his head and focused on his mother. "Okay, first question. What is going on? What are you keeping from me? Why does no one discuss this serial killer?"
Lily sighed and nodded. "Okay. I will tell you. First I will introduce you to Bellatrix Slytherin." She waved her hand at Bella. Harry looked over and Bella waved at him while smiling.
"Hello, Harry. It is a pleasure to see you again. If you ever feel the urge to bend me over and have your way with me. You can feel free to do that." Bella told him casually as she reached up and groped her breasts. "I also need to introduce you to my daughter later."
Harry looked back at his mother who was shifting nervously. "Stop stalling and explain, mother." Harry demanded and Lily blushed a reaction that Harry was not expecting.
"Okay… the truth is… I lied." Lily sighed before she continued. "I lied about who your father was. You are not Harry James Potter, son of James Potter, my husband."
"What?" Harry frowned. "What happened?"
"I cheated on your father. In fact I have been cheating on your father since we started dating in Hogwarts." Lily answered with a sigh. "Tom Marvolo Riddle is your real father. Although his real name is Tom Marvolo Slytherin since he was the heir to Slytherin."
