"I wouldn't be asking if it wasn't important Giles" James said shortly "I just need you to look after Jason whilst we go into hiding with Harry because Voldemort is coming after us.

"So you want to take one son away from his mother so that he would be safer?" he said "why not let me take Harry as well I have talked to Joyce Summers her daughter Buffy is the slayer when she grows up we just have to wait for that James let me take Harry with me"

"No" James said firmly "now can you take Jason for me?" and Giles nodded

"Uncle Rupert" Jason said walking into the room Jason would be three this year he looked different to James where as Harry was his father's little double Giles remembered what James was like at Harry's age being James's uncle but Jason had always called him uncle Rupert.

"Hey buddy" he said "did your daddy tell you about our party?" and Jason nodded James and Lily had thought it was best to tell Jason he was going to a party with Giles and then they would put him under a memory charm until he was older or until Voldemort was gone at least.

"Am I asking too much?" Giles asked

"No" Joyce said "you want to keep your promise to James and Lily I will keep Jason safe and Harry has to go to the Dursley's?"

"They are the ... closest blood relation to him" Giles said "a watcher is going to look out for him and aurors as well Mad eye is so pissed off he offered to watch Harry day and night when they have all of the death eaters which might take awhile especially the demons and everything else"

"Ok" Joyce said "do you want me to adopt him?"

"I doubt that would be a good idea with the prophecy" Giles said and they both grinned "hopefully one day we can reunite Jason and Harry I don't know when that will be maybe when Harry goes off to Hogwarts" and Joyce nodded.

"Time to get up Buff" Jason said to his friend even though Joyce was Buffy's mother and raised Jason, Joyce had stayed true to her idea and had not adopted Jason so that they where best friends rather than brother and sister if the time came for them to be more than friends.

"I don't wanna" she huffed

"Fine" Jason said "I'll tell Giles miss perfect slayer couldn't get her ass out of bed in time and I will get more time to train then" and she quickly sat up

"We have training today?" she asked and Jason nodded with a grin "aw i told Willow we would go shopping today just the two of us"

Jason, Willow and Buffy where like the best of friends and one of the reasons why Buffy's term as the slayer had gone so smoothly as Jason was a wizard which it took 3 months to convince him and he was teaching Willow magic still and with Buffy being the slayer it made them damn near unstoppable.

When they went downstairs they where surprised to see Giles and Willow downstairs waiting for them with three other teenagers.

"Jason and Buffy Summers meet Harry Potter, Hermione Granger and Ronald Weasley" Giles said "Jason this is your little brother"

"Holy" Buffy started

"Shit" Jason finished

As everything was talked over Jason sat with Buffy close to him which surprised both Joyce and Giles as they expected that as soon as Jason was told he was not a Summers he would be hurt and want nothing to do with Joyce or Giles and then he remembered the memory charm they had placed on Jason did not take away his memories when his other ones returned just added them together.

"So why now?" Jason asked

"Well Voldemort is going for a big war to finish this thing" Harry said "and we need help" and Jason smirked and looked at Buffy long had he wanted a little brother or sister to help and Buffy was the closest he had been with her being younger than him.

"We need training with this" Harry said and summoned the sword of Gryffindor into his hand

"Shit" Buffy said "can I see it?" and Harry handed it to her like it was Christmas morning and Buffy was 6. James grinned that was the best thing about Buffy she was smart and funny and cute but she also still had a slight innocence about her Jason had made sure no boy even thought about touching her in that way and that was before he realised she was a girl. Jason then took the sword in his hands once Buffy had finished looking at it and it glowed causing Jason to look up from the sword and at Giles.

"You got some explaining to do" Jason said with a grin.

"You're a reincarnation" Giles said once they had all sat down again and as before Buffy and Jason where sharing the same seat not that they where dating they were just that close that they didn't mind sitting in the same chair or Buffy on Jason.

"I'm a what?" Jason said

"You've died before" Buffy said quickly "of who?"

"Godric Gryffindor" Giles "judging by the way his sword reacted to you"

"Holy crap" Jason said and Buffy smacked his arm again and he grinned "so what now?"

"We need help" Giles said "Voldemort is killing everyone even the demons are helping him"

"I wondered why we were having a slow month" Buffy said "they were all your side of the water"

"Yes so we need to go and help" Giles said adjusting his glasses

"What about the vamps and stuff over here?" Buffy asked

"I can do it" Willow said "it will be easy with all of the spells that Jason has taught me"

"I can leave you some stuff as well" Jason said "you know like fire spells and stuff" and Willow nodded she was at the equivalent of 6th at Hogwarts from what Jason had taught her from all the books that Giles had given him.

"So when do we have to leave?" Buffy asked and she felt Jason tense and knew what was going to happen the next time they were alone he was going to try and get her to stay rather than to join the war. As they walked up the stairs to Jason's room to pack Buffy quickly closed the door and folded her arms over her chest

"So lets hear it" she said

"Huh?" Jason asked confused

"The your not coming with me speech" she said shortly "I am 4 months younger than you Jay I can look after myself"

"I know" he said sighing "but no you mean to much to me"

"As a friend or little sister?" Buffy said darkly

"Neither" Jason said shaking his head "Willow is my best friend Buff I always thought we where more than friends like an old married couple without marriage or sex" and then he grinned and the angry look on her face melted like it always did.
