A few weeks have passed after his marriage with Narcissa, and she is settled down in the manor. She will be going to help Andi with the politics and management of the houses as she is more knowledgeable than her as she has been managing the Malfoy manor for many years. She spends some time with Harry's other fiancé, but most of her time is spent with Andi and Sirius as they are spending time after almost 20 years.
__________(Hogwarts)__________
Harry is currently sitting in the headmaster's room with all the professors as he calls all of them to get the results of all the changes he did in the education of the students. He wanted to know all the additions the professor made in updating the course, even though he gets feedback from the girls and other students the course is updated in the background as some subjects required more time to update as they have not been updated in over a half-century and for that subjects, he can't get results from them.
"Most of the subjects are up-to-date with the current information including the new subjects you asked us to teach. The only subjects that take a few more weeks are ancient runes, defense against dark arts, and charms as we have to screen every spell and have to find if it is safe and worthwhile to teach the students."
Professor McGonagall gives Harry the report about all the updates in the course.
He is happy with the changes as they will allow the students to gain more knowledge and not learn something which is probably outdated for more than a decade.
After it is done all the professors leave the room, and only Dumbledore and Harry are left in the room.
"Mr. Potter"
Dumbledore calls Harry as he wants to talk to him about something.
"Yes, Headmaster Dumbledore."
Harry speaks as to what this old man is going to say.
"Mr. Potter, what happened in the chamber?"
_______(Past few weeks)________
Dumbledore is sitting in his chamber and thinking about all the things that have happened over the past few months and want to get the answer to why things are not the way he wanted them to be.
He started to put all the things he knew:
1) Harry finds out about his inheritance not only Potter but many more.
2) He met with the Andromeda Tonks and got under her guardianship.
3) Sirius Black is free.
4) The Potter alliance is reinstated.
5) Harry's distrust in him.
He started finding out when things were going to change at the start everything was going as he wanted it to be, but suddenly everything went wild, and he couldn't control it.
When he started doing it everything led him to the chamber. He knows that something is happening in the chamber, but what? He can't put his mind on what happened, he tries to think about all the possible things which happen in the chamber.
He thinks that Tom take over Harry's body but this is trashed immediately as he knows Tom can't hide his presence from him for months. He then started about other things but he couldn't point out anything as only Harry and Ron were present there and only Harry knew what happened so he decided to ask him directly, as he didn't have any other option.
_______(Present)_________
"Mr. Potter, what happened in the chamber?"
Dumbledore asked.
"What do you mean, Headmaster?"
Harry replied without showing any emotion as he didn't want Dumbledore to know what happened in the chamber.
"I want to know what happened in the Chamber of Secrets when you saved Miss Weasley from the chamber?"
Dumbledore asked again as he knew that something must have happened that Harry was trying to hide, and he wanted to know it.
