Million thanks to my beta x-Xanti-x. You are the best!

Thanks to everyone who reviewed. Please keep this good habit for a very, very long time.

Meet the godson

Harry and Hermione levitated Sirius to the bedroom on the first floor, the same one where they first met him and used the spell Sirius and Remus used on Wormtail to change him back to his human form.

Hermione sat down onto the bed and waited patiently for Sirius to wake up. One look at her husband told her that he slipped back into his leader mode and decided to hide all emotions from his face. Hermione knew that under the mask he was just as nervous to see his godfather as she was.

'It must be really hard for him to see Sirius alive again, after 8 years,' thought Hermione and she was about to get up from the bad and go to her husband and try to comfort him but, as if reading her mind, he held up his hand, effectively stopping her from approaching him any further.

They spent a good ten minutes in utter silence, when they heard Sirius groan and he looked in his direction, right on time to see him lift his head and look away in an instant, mumbling something about hitting his head hard and loosing his sanity at last.

"I can assure you that you are completely sane and well." said Hermione, using her professional voice.

"If you are from the Ministry, then please, tell me, why am I still here? Why haven't you taken me to Azkaban yet? Or is this personal revenge?" asked Sirius, still not looking at them. "And it was a very stupid thing to try and impersonate my godson. I'm not stupid; you know and are aware of that my godson is 13."

"We are really glad that you are not stupid, Sirius. It would be quite disturbing, to tell you the truth. And no one is trying to impersonate me. I really am Harry James Potter, the son of your late best friend, James Potter, or Prongs." said Harry with his voice lacking of any emotions all the time.

"And I should believe you this? Moony could have told you all of the things. To tell you the truth, I'm really surprised that you haven't found me earlier."

"Remus never betrayed you in any way. Of course he hates you right now 'cause he thinks that you have betrayed him, the Potters and the little saint sodding git, Pettigrew." informed Harry his godfather, letting Sirius hear the anger in his voice.

It seemed that was the only thing Sirius needed to hear, as he quickly looked up, meeting the eyes of his godson for the first time for him at least.

"Lily's eyes…" he whispered and Hermione could see that the whole thing was getting harder and harder for Harry so she decide to talk herself instead.

"Yes, he has Lily's eyes and all. We've heard that countless times. Look, we haven't got much time, so I'll be as quick as I can. I know it is going to be very hard to believe all the things I'm going to tell you but please listen without interruption.

"We are here from the year 2004. As I've told you before he," said Hermione, nodding towards Harry, " is really your godson, even though not the one from this current time, but still the son of Lily and James Potter."

To make a long story short we arrived here on the first of September, due to a potions incident, and have been in Hogwarts since then. In our third year, when you escaped Azkaban, we, along with our other best friend and Remus, found out about you innocence and Wormtail's betrayal…"

"That little…" started the escaped prisoner, but Hermione cut him off.

"As I was saying, before you so rudely interrupted, we've been told the real happenings of the night Voldemort killed the Potters and the day you've been taken to prison and helped you escape from the dementors. These are the things you need to know in a nutshell. We came here tonight to help you catch Wormtail. That is, if you want us to help." finished the woman.

"So, let me get this straight. You are from the future and here to help me." He asked then started to laugh wholeheartedly. "This. Must. Be. The. Best. Bloody. Joke. I. Have. Ever. Heard. In. My. Entire. Life." Finally managed to chock out Sirius, still rolling on the floor, tears spilling from his eyes, he was laughing so hard. "Even James and me wouldn't have been able to think something so ridiculous and brilliant at the same time." continued him.

"You think that this is funny? Do you think so? Now let me tell you one thing…" started an obviously angry Harry. Sirius stopped laughing the instant he heard Harry's voice, it was so cold. Even Hermione shivered a little.

"Harry…" started the woman but didn't get to finish the sentence as Harry held his hand out the second time that night and said:

"No, Hermione. Let me finish it. "said he, allowing his voice to lose some of its coldness, just for his wife, but when he continued he still sounded as cruel and cold as the iciest as the coldest iceberg. "It was not my desire to come here and see dead friends and teachers whose death is my fault. I never wanted to be here and I still don't want to, but I have to do anything in my power to at least make my stay as useful as it can be. I came here to help you and I may have already changed everything just by coming here. If you don't want our help then we will go away and leave you on your own to eat rats and other dirty things. It's not my concern. But if you chose to let us help then you have to take us seriously and no Sirius-serious joke, please." finished Harry with a hint of humour in his voice at his last sentence, which only Hermione noticed.

"Okay. Let's say I believe you. But how do I know whether I can trust you or not?" asked Sirius.

"God, Sirius!" exclaimed Hermione "If you believe us then you should understand that your godson would never betray you."

"But do I know it for sure? I've never met either of you so there's no possible way for me to know you two. For all I know, Voldemort could be alive in the future and you two could be working for him."

"In that case we should be leaving, shouldn't we, Harry? It seems we are not wanted here. Good bye, Sirius Black. Maybe once you'll understand the huge mistake you've just made. And I wouldn't worry if I were you. No one will find out that you are hiding in here. Not from us at least."

With that the two left a stunned Sirius Black behind themselves and, just like Hermione said, in just a few minutes he is going to realise that he just refused the best offer he could ever get in his present "murderer" status.

LLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL

A few days after their encounter with Sirius Black, morning found Hermione in her bed alone. She missed Harry terribly from her side. Of course she spent most of her days with him, but that's not the same. They never did things like a normal couple should. Of course they weren't a normal couple.

Hermione never had the privilege to go out on a date with her boyfriend, to wake up next to her lover and just lay there, next to him in a complete, but comfortable, silence or just have little morning talks. But she had Harry and that made up for everything. And they will have their whole lives to make up for the lost things. Or she hoped so.

The truth was that she was afraid of the future and what would happen in it. She trusted Harry and his powers and knew that he is going to survive the Final Battle, the only question was: when? Today? The next week? The following month? Or the one after it? For all they knew it could take years, hell, even decades!

She wanted to be able to enjoy the life with Harry. She wanted the small things. Little talks at night after a tiring day of work, cuddling before the fire in silence, have children….

Yes, she wanted children. A lot of them. Of course she knew that these times were not the times a child should live in, but still. She understood that Harry was afraid of losing her and losing a child would be just as bad, if not worse. On the other hand she knew that Harry always wanted a big, loving family and would give anything for it, but he didn't want to raise a child in war times either. They never talked about having children and Hermione strongly suspected they won't either, not until the end of Voldemort and the whole war.

That was the moment she noticed that, while thinking, she unconsciously got up, had a quick shower, brushed her teeth and had gotten dressed. She was heading for the portrait hole when it suddenly opened and revealed Harry standing there.

"What would you say to a late training session?" he asked.

"A late? Harry, it's 8 o'clock in the morning. You call this late?" she asked teasingly, feeling particularly daring that day. "Don't answer. Let's go." Hermione was about to leave her room when Harry grabbed her arm and pulled her back, capturing her lips with his. He started to back until he felt the couch behind hem and collapsed onto it with Hermione sitting in his lap, kissing his neck.

He was about to take off her T-shirt, when the entrance of the room suddenly opened just to let Dumbledore in. The couple stopped their current activity, but Hermione stayed where she was as Dumbledore found them, there was no way they could explain this, so why hide something so obvious?

She turned around in the lap of her husband while Dumbledore approached them.

"Lovely morning, isn't it?" asked the headmaster smiling.

"It was, until you came in. How can I help you?" asked Hermione, clearly irritated.

"You know in some places it is considered rude to leave the guest standing while you are sitting on a comfortable looking couch." said Dumbledore.

"Yes, I have manners, thank you." said Hermione in a too sweet voice. "I'll ask once again: what do you want?"

"First of all I must tell you that I don't like the idea at all, and I still don't trust you, but Mr. Lupin requested this as he seems to, for some reason, trust you. Due to his condition, he couldn't come himself, so he asked me to tell you that he wants you two to take over his lessons today."

"It's full moon already?" asked Hermione while looking into Harry's eyes silently asking whether they should or shouldn't accept the offer. Harry only shrugged and mouthed: 'Anything's better than Snape.'

"If Remus wishes this then be it. We'll do it."

"In that case I would hurry as your first lesson starts in just 10 short minutes. It's third year Gryffindors and Slytherins." With that, and a wink, which was kind of strange from a man who thinks they are evil or something like that, he left the room.

"We should be much more careful if we don't want to reveal too much of the future." said Harry slowly, and then got up along with Hermione.

"Do you think it was a wise thing to accept his offer?"

"Definitely not." And with that Harry left the room too with Hermione following him.

They arrived just on time before the DADA classroom and let the stunned third years in.

"I guess we don't need to introduce ourselves. Professor Lupin does not feel well today so we are going to take his place today, but don't worry, he'll be back tomorrow. Let's see. You may put your books away. You won't need them today." started Hermione and looked at Harry who was staring back at her with questioning eyes.

"Today we are going to talk about…" continued Hermione but Harry interrupted her.

"Wait a minute. One student is late. He should be here in about 5…4…3…2…1…"

And the door suddenly swung open with the younger Harry in the doorway.

"Sorry Professor Lupin, but…" they never found out what he was about to say as he froze in mid-sentence staring at the two time travellers in the front of the classroom. "Where's Professor Lupin?" he asked suspiciously.

"He did not feel all right this morning and decided to take the day off. Now, sit down and 10 points from Gryffindor for being late." answered the older Harry with the whole class staring at him dumbstruck.

"But you know the reason for me being late!"

"Yes, I do, but you were still late. Now sit down."

Hermione waited for Harry to settle down and continued the lesson as if nothing happened.

"As I was saying before, today we are going to learn about dementors." Once again it was the class's turn to stare unbelievingly. "Now, Harry is the expert in that department, so listen to him carefully as you may learn lifesaving information."

For a long minute, Harry, the older, only stared at Hermione sending murderous looks in her direction, but eventually directed his attention to the class and the task at hand, namely teaching.

"All right. Most of you know that dementors are the guards of Azkaban and feed on happiness. That's the reason why Azkaban is so dreaded. Most of the prisoners go insane in a few weeks. No one can control them. The ministry foolishly thinks that they control the dementors. Well, that's not true as you'll see it in just a few days." at this everyone stared at him like they thought that he was crazy, expect for his wife, of course.

"The only thing that a dementor is interested in is its hunger. They'll do anything to quench their hunger and that's why they obey the ministry. If there was anyone who offered them more souls they would turn against the ministry within the blink of an eye.

"Even though they feed on happiness it's not their only "food". They can suck the soul out of every living thing and that's what you may know as the dementor's kiss. Not a pleasant thing. Just a simple example. Let's take Ron here. To a dementor, simple happiness is like for Ron eating only the amount of food Hermione, here, eats and the soul is the amount Ron usually eats. Happiness is only enough for an hour or so, after that they need to eat again.

"A dementor never takes their cloak off completely, but under it their skin is rotting and it smells like hell. The cloaks are charmed to contain that smell. The dementors are not pitiful. They do not distinguish between evil and good, it does not matter to them whether they harm an innocent or a murderer. The only thing that matters is food.

"An average dementor lives for 500 years or so. According to some legends, the first dementor was man who lost everyone dear to him until he lacked all emotions and started to use his magic to collect the happiness of others around him, until he became so desperate for happiness that he sucked the soul of his victims out and when his time came to die, he couldn't die, as he had hundreds of souls inside him. Even though he couldn't die, his body aged with him. But this is only a legend.

"Dementors affect those the most who have very bad memories. The only defence against dementors is happiness. There's a spell that can drive dementors away, but it's a hard spell and not because you need much power to cast it. No. Almost everyone can master it with practice and the right memory. The hard thing comes when you have to use it anywhere near a dementor.

"The spell feeds on happiness and you have to think of a very, very happy memory of yours. The dementor feeds on your happiness and it's awfully hard to find the power within you to think of your happiest memory when a creature tries to suck all of your happiness out.

"The indication of the spell is Expecto patronum. The words come from Latin and means 'I expect you, my guardian'. The spell summons your inner guardian in the shape of an animal. With most, but not all, people the animal is their animagus form. Any questions?" asked Harry after his speech with raised eyebrows.

After a few moments of silence Hermione raised her hand and when Harry nodded to her to speak she asked:

"Have you…have you ever seen a dementor without its cloak?"

"We both had the misfortune to have a look at their rotting faces, yes." He answered indicating to his wife when he said we and both.

"Am I right in my assumption that you can do the spell?" asked another girl rather daringly.

"Yeah, I had to learn it. You know, bad memories." answered the questioned, his face darkening.

"Can you show us, please?" asked Parvati Patil, which surprised Harry the most as she never, and I mean never, talked in class. Not to the teachers at least.

Without answering Harry drew out his wand and muttered the indication. He didn't want to reveal neither his wandless abilities nor the ability to cast such a hard spell silently and wandlessly.

The usual stag erupted from his wand in its whole glory, leaving the whole room except for the husband and wife, awestruck.

"Is the stag your animagus form?" asked someone from the back row and when the older Harry looked up he met the eyes of his younger self.

"No. My father's animagus form had been a stag. That's why I have him as my patronus, even though I didn't know this at the time when I learned the spell.

"When was that? Or when will be, to be exact?" asked the ever curious 13-year-old Hermione.

"He learned the spell in his third year." answered the questioned's young wife. Everyone stared at both Harry's in awe, but fortunately the bell saved the time travellers from further questions.

I hope you've enjoyed this chapter and don't forget to review! It always makes my day.

I used most of the informations on te dementors from the HP books (those I remebered of) and I created some that I couldn't find in the books.

Have a nice weekend!
