Harry Potter and the time travelers

Chapter one

Its been a while since the kids tried to save Cedric Diggory, the son of Amos Diggory and a good friend of Harry's. All of them tried to explain Amos that they tried so hard to save him..but they failed. Everybody was ready to get over this, but this unexpected visit changed everything.
"Amos...im sorry...they tried" Harry said.
"Nonono....My boy..my handsome boy...". At this moment, Amos was already crying. He cant just let this go...
"We really tri..."Albus wanted to calm he down but was  cut off by his words:
   "Kid...let me tell you something...Voldemort didn't want to kill him...Noo...Cedric could have had a happy long life...But he decided to help your father.. A lot of people died helping him...AND YOU "said Amos looking at harry "you dont know the feeling of coming home alone...to be all alone.... to see your son in every little corner of your hause...knowing that him isnt here anymore...to know that..that he died so young..." Albus couldn't look a way from the man in front of him. His words... his words about Cedric were in the boy's  head.

~Time skip~

After almost three months everyone seemed to have forgotten about Cedric. Everyone except Albus. The things that Amos told him in that day were still in his head. He felt so bad for Amos...for Cedric..and he didn't even meet him. Albus was looking on the window, thinking about Amos's words when James came in the room.
    "Why so silent, brother?"
    " We tried...we tried so hard..but he didn't want to listen. He..he..he could have been alive by now...if he listened to us."
    "You still think about that..." Albus nodded.
    "But why?...why are you so affe.." James tried to say something...only to be cut off by Albus
    "Cause we dont know how it is to be alone..all alone. We have eachother...We have a family...a big one. The only person Amos had was Cedric..". Silence. James was looking at the floor..kinda sad. Silence...an awkward one..until Albus's words decided to break it"
    "We need to find something.. We need to save him.."
