They had been meeting in Stark Tower when they all heard a pop. The Avengers were official disband, but they still meet on occasion. It was to mostly keep up with each others lives, I mean if you save the world together a few times then you at least become friends. When they heard the pop, everyone grabbed a weapon and went to see what it was. To say they were shocked was an understatement. There on the floor, covered in blood, was Loki and he appeared to be holding a young man.

"Brother, what are you doing here? Who is that? Why are you covered in blood?" Thor asked. The others decided to let him take lead because he had the most experience with Loki.

When they got no response, all the Avengers looked worried. They know that silence was not like Loki. he was more likely to give you a cutting remake then to stay silent. Thor decided that if he was going to find anything out he would have to approach his brother.

When he got closer, he saw that the young man was extremely injured and that his brother was trying to heal him. Loki's eyes were golden, like that of a wolf's. Thor didn't know what was going on, but he figured that this young man was important to his brother. He went back to the others, because if he tried to talk to Loki or try and move them, Loki would react violently because he was running on instinct.

"The best advice I can give to let Loki finish healing the person then try to talk to them. As it is, Loki has retreated into himself and if we try to move them he will try to kill what he perceives as a threat." the others nodded as the went back to the table.

"What do you think about that?" Tony asked everyone after they got their drinks. everybody looked at Thor.

"From what I can tell, the young man is important to Loki. I think that he brought himself to me out of instinct, because I am family. Also, there is some sort of bond between the two, and Loki has gone... feral, is the best word I can think of. Because he is a shapeshifter he has the instinct that go with the animals he turns into. It is those instinct that are in control right now, so if anyone that is not family or mate, comes near him, it could be very bad." Thor said, sighing.

"Do you know what type of bond that they have?" Nasha asked.

"From what I can tell, it is a mate bond that hasn't been… finished." Thor said slowly.

"So what Loki and the mystery person have a mate bond? What does that mean? Is it like a wolf mate? If so, the fact that it is incomplete mean that they haven't have sex?" Clint asked really confused. Thor winced and glared at Clint, who had still not realized what just came out of his mouth.

Natasha smacked her boyfriend upside the head, and said, "You idiot. Do you even hear what comes out of your own mouth? Now, you will apologize and Thor, would you please answer the question?" Bruce raised an eyebrow at Tony at the actions of the "hidden" couple.

"I have no idea why I am apologizing, but I am sorry if I said something offencive." Clint said still completely confused.

"To answer your questions, yes they have a mate bond, and it is like that of a wolf's mate bond. This bond means that they are drawn to one another and once it complete, they will keep the other stable. To complete it it you have to have sex." Thor said, worried about what they would think.

"Well atleast someone will be able to to keep Loki in line and prevent him from going crazy again." Natasha said. "Any ideas on who the mystery person is?" They all could detect the nervousness in her voice.

"Um… No, but do you have any ideas?" Steve asked.

"It depends on the color of his eyes, but he looks just like my favorite niece's husband. If he has Lily's eyes, then he is my great-nephew." Everybody but Clint started, because it was so easy to forget her age.

Clint just raised an eyebrow and said, "So I have a great-nephew in law? What about his mother?"

"His mother was killed. I don't know where he has been living, but I hope that it wasn't Petunia." Natasha answered.

"Who is Petunia? Why would you hope he didn't live with them?" Tony asked.

"Petunia is Lily's older sister. Petunia hated Lily, so I fear that if Harry was raised with her, he would be abused. Her husband has always given me the creeps." Clint raised his eyebrows at that last fact. Any man that Natasha the creeps, general had a "peculiar" taste in bed partners.

Before they had time to ask anymore questions, Loki came in. Leaning on his side was the young man that had some with him. This young man was short, but lithe. His black hair made a crow's nest on top of his head, and he had the clearest set of emerald green eyes. The all could see that those eyes had seen far too much for such a young age.

After seeing his eyes, Natasha shucked in her breath, and in a broken whisper, "Ry."
