Stiles turned up at the loft and was stood at the bottom of the stairs, he was just about to climb up the spiral stair case when he hears "What? This isn't about me winning? You left him you broke him and your acting like the wounded party. Now I find out that you're already mated to MY MATE!" Peter snarled, Stiles froze and felt his heart race as he listen to them. "We are going to tell him." Peter snapped at his nephew

"Stiles is happy with you, why does he need to know?" Derek hissed, Stiles heard something smash and realised that Derek or Peter must have thrown something.

"He needs to know Derek because of everything that is going on in his life he needs to know!"

Both wolves heard a thud and rushed out the room and looked down the stairs to see their mate passed out on the floor. Peter growled at Derek as he rushed down the stairs to pick up the teen "Derek do you understand what happens when mate isn't there when their child is born?" He asked him

"The child will die, Stiles is carrying your children." Derek tells him as he walked down the stairs and over to the sofa where Peter placed him down gently

"As true as that is all mates have to be at the birth!" Peter growled. Derek flinched as he was the alpha red eyes flashing at him and it made him drop into a chair next to Stiles and rubbed is hands over his face.

"I…I…I left because I was scared, I died and when I came back my head was cloudy nothing was clear and I forgot about the pack I forgot about Stiles it was like I couldn't remember anything." He told Peter, his uncle was still frowning at him but looked likely he was going to kill him. "When things become clear I lost 11 months I didn't know what to do, but I decide to come back to fix the damage but Stiles seem to have moved on with you." He told him. Peter sat on the coffee table and pressed his hands to his mouth

"Have you told Stiles any of this?" He whispered

"No, he refused to talk to me for the first few months." Derek mumbled

"You're a fuck arse hole." Stiles mumbled.

Both wolves turned to look at him and saw Stiles starting to sit up his hand pressing to his stomach where they could both see a small swell. "Your both arse holes but it seems I am stuck with you." He said, as he rubbed his eyes

"Did you hear what was said?" Peter asked as he sat next to Stiles and took his hands

"Yeah, Derek left because he couldn't remember and I'm mated to him and you." Stiles told him.

"We need to work thought this my little fox, this will make us stronger." Peter smiled softly, Stiles looked up at him and sigh

"Stiles…" The teen kissed Peter on the cheek and then got up walking over to Derek and kissed him on the lips

"Fuck this up and I will cut your junk off and make you eat it." Stiles warns "Now if you don't mind am going up to the bed room to sleep." He told them as he turned to walk upstairs.

Couple of days later…

Stiles thought about his stalker and thought about who could it be and the only person that that kept popping up was Theo Raeken. "Shit." Stiles thought as he stood back from his board and looked at the bigger picture. He picked up his pack phone and called Lydia over and it wasn't long before the red turned up with Kira and Malia, Stiles took them upstairs and showed her the board.

Lydia looked at the board and traced the strings that were across the board, Stiles left Theo's picture off the board he wanted to see if Lydia could put two and two together. "Stiles do you know who it is?" Kira asked

"I have a theory." Stiles told her "But I want to see who else makes the name connections." He told her. Lydia turned to look at him and frowned and Stiles knew that Lydia had figured it out.

"You sure it's him?" She asked

"Not a 100%." He told her, Malia and Kira looked at each other before looking at the board.

It took them a little longer for them to figure out but when they did they both turned to look at Stiles "Theo." They said, both with a fearful look, Stiles nodded and sagged on his chair letting out a sigh

"Theo? We haven't seen him in 3 years not since he attacked you." Kira said as she sat on the bed

"I know… but it makes sense doesn't it, he was obsessed with me all away though school."

"Stiles he…hurt you." Lydia said, making the teen nodded as she warped his arms around himself

"I know he did Lydia."

"Wait didn't he get killed?" Malia asked,

"No he didn't but after he left we found out he killed his sister and a few other students." He told her. They decide to call the rest of the pack to tell them what they thought, Stiles was fearful of what Theo would do if it was him. He hadn't seen him in years the last time was traumatic his father ended up in hospital and he also lost Scott and he ended up being pinned to ground and abused by Theo then Parrish saved him. Stiles shook his head thoughts and headed down the stairs.

Lydia and Kira were already down stairs while Malia was in the bath room. Stiles was lost in thought as he reach the top of the stairs, he stopped when he thought he saw something in his father bed room. He knew it wasn't Malia because he could hear her washing her hands in the bathroom. He walked towards the door only to see a figure come flying out and push into him the wall Stiles gasped as he lost his footing on the stairs his hand missing the banister sending him falling down the stairs. The last thing he saw was the intruder's face before he ran into Stiles room. "OH GOD STILES!" Lydia cried out as she moved quickly to her unconscious friends side as Maila ran to Stiles bed room as she saw the intruder disappear though the window.
