Disclaimer: Even if the plot bunnies are still possessing me, I don't own Harry Potter or the Avengers. I also have zero skills at stealing things, so neither of them are likely to belong to me or Sophus anytime soon. (No, Sophus, it's not a bad sign that the first way to obtain the rights to these creations was illegal. It just means I've been spending time writing about Loki. Writing can't be a bad thing, can it?)

AN (Caela): So, first off, thank you all so much for your support! Writing this and receiving all of your reviews has been a truly amazing experience for me, so thank you! This is the final chapter of this fic. It felt right to end it after Harry was somewhat settled into the tower. I will admit to anybody who asks that I am terrible at endings, hence why this is my first multi-chapter fic that isn't just a series of one shots. I am going to be writing more prequels, and I have a short story about Harry's Hogwarts letters planned. However, other than that, I have nothing else planned. Anybody is welcome to write more in this universe or using this story as a base, I just ask that you find some way to tell me where to find it. I would love to see anything that you do with this!

This actually went on a lot longer than I expected . . . I honestly just wanted to make a fic where the Avengers thought somebody was Harry's parent, but he turned out to be the son of Lily and James Potter. I thought it would be funny. And I can honestly say that I warned you in the description. He is just also legally the son of the Avengers now.

Sophus betad this chapter . . . Like the first six chapters . . . And the seven other stories I've written before this. The trend continues.

Steve was on Hawk-sitting duty.

Though none of the Avengers had been happy to leave Harry and Loki alone during a delicate magical procedure, Clint was the only one who had been foolish enough to try to sneak into the room with them. He learned rather quickly that the ventilation system did not protect him from being detected by Loki.

This meant that Steve was stuck watching Clint. In the words of Natasha:

"I have to deal with him on a regular basis, Tony has already disappeared into his lab, Bucky is too worried about Harry to watch him properly, I'm not going to subject Bruce to him, and I don't quite trust Thor to be able to keep track of him for that long."

As most of the others had left at the mere suggestion of having to keep track of Clint, Steve was really the only option for Hawk-sitting if Natasha refused the job.

The only one left with them was Bucky, who was currently sitting in a chair glaring at the door. His posture very clearly said that anyone disturbing him would be risking severe bodily harm.

At this point, Steve was almost willing to risk it if he didn't have to deal with another one of Clint's escape attempts.

Odin had long since learned that he should go along with whatever his wife had planned if he wanted to keep his sanity. However, there was one thing about her current plans that baffled him.

"What do you mean grandson?"

"Our grandson, of course. Loki's son. The one that we are currently going to visit on Midgard. Are you ready to depart yet?"

That did not help Odin's confusion. As far as he knew, neither of his sons had children. Odin was also very aware that if he wanted to live, he would not get in between his wife and his grandson.

Wisely, he answered only with a yes.

Frigga was taking a great deal of pleasure from her husband's confusion. You wouldn't expect it from the dignified queen of Asgard, but she loved to trick people. Where else would Loki have gotten it from?

Her son still had a lot to learn about the art of not getting caught.

She had been keeping an eye on her son and grandson until she knew it was safe to visit them.

"And what do you think you are wearing? You are not going to wear armor to Midgard! We are visiting our grandson, not waging war!"

Oh yes, Frigga was getting every second of blackmail she could out of this trip.

"Mother! What are you doing here?" Thor had never expected his mother to leave Asgard. She tended to stay with her husband, and Odin generally only left Asgard during times of war.

"I'm here to visit my grandson, of course! The grandson that you never told us about. We will be talking later." Thor winced, then looked at the doorway, astonished.

His father had just walked into the room.

His father was not only on Midgard, but in a suit, and not armor.

His mother was truly a miracle worker.

At that moment, Loki walked into the room, clearly exhausted. he was carrying a sleeping Harry, who Frigga quickly took out of his arms.

From the way Frigga was looking at her sleeping grandson, Odin could tell that there was no way she would be less than overprotective of him. It didn't take divination to predict that there would be many more visits to Midgard in his future. As much as he may grumble about leaving Asgard and dressing strangely, it was worth it to see his wife so happy.

It was probably time to start talks with the leaders of Midgard about setting up an embassy. It wouldn't do to leave his grandson unguarded and vulnerable to attacks by enemies.

He would make arrangements to protect his grandson for Frigga's sake. It couldn't possibly be that he was already starting to care for the child in his wife's arms.

No, it was purely for Frigga's sake.
