Hi guys, I hope you enjoy this chapter :) There will be a couple more crossovers.

To guest what's going on with Lewis will be explained in this chapter :)

Ash's heart ached as he wrote his letter, he knew that his Emma and his friends wanted to run with him, but after everything Denman had put him through he realized how dangerous she truly was and couldn't place them in danger. He just hoped they could forgive him for this. Ash grabbed the spare go-bag that Zane had and after checking his plane tickets had been downloaded to his phone sneaked out. They always made sure they had friends that they could stay with in case this happened and as Denman had been closing in on them, Ash had arranged a visit to his friend Stiles in Beacon Hills in America and Stiles had been more than happy to let him stay.

Ash was relieved his taxi wasn't late and jumped in. He wished he didn't have to wait two hours for the plane to leave, it would give Denman more time to find him before he could leave. When he had paid the driver he ran to the airport, it took a long time to get through security and it put Ash more on edge, he was constantly looking over his shoulder afraid that Denman would appear at any moment. Ash sighed in relief when they believed the fake ID, he kept the same photo but Zane had a friend who changed his name so that it was harder for people like Denman to track them.

Making sure to pull down his hood to shield his face, Ash made his way to a café to get a drink to try and calm down. Ash checked his phone and sighed when he saw a lot of missed calls and texts, he felt so guilty but he continued to ignore the incoming calls. Ash's eyes widened in fear when he saw Denman, a little while later, who smirked when her eyes locked with his. She made her way over to him and Ash ran, Ash ran and ran until he ran into Lewis who grabbed his wrists.

"Lewis please let me go!" Ash said panic stricken.

"I'm not trying to hurt you, I want to help you".

"What? Do you really expect me to believe that?"

"No but-" Lewis cut himself off when he saw Denman and ran dragging Ash with him until they were a safe distance away. "I'm so sorry for hurting you Ash, I hated having to hurt you it was the hardest thing I have ever had to do but it was the only way for my plan to work".

"I don't understand", Ash said warily.

"I had to make you and the others believe I had betrayed you so I could erase all the information Denman has on you". Lewis brought out a hard drive. "This has all of Denman's information, you don't have to believe me now but check this when you get the chance". Ash reluctantly took it.

"How do I know that you erased Denman's version? You could have just copied it and not erased it to trick me".

Lewis sighed, "You have every reason to not believe me, but I care about you so much and I can't let Denman catch you again. Please let me help you".

Ash scrutinised Lewis, he seemed sincere but he wasn't sure if he could trust him after what he did to him. But Lewis had just helped him get away from Denman when he could have turned him in. Part of him desperately hoped Lewis was telling the truth and hadn't betrayed him, he had been though enough betrayal. "Okay but this doesn't mean I have forgiven you or that I trust you".

Lewis nodded and smiled hopefully at him, "Come on it's not too long until your flight now".

Ash followed Lewis hoping dearly that he wasn't leading him straight to Denman. Lewis took him to another café and bought them both drinks to pass the remaining time. Conversation was very awkward and Ash was glad when it was time to leave. They ran to the gate constantly checking that Denman hadn't found them. When Ash was about to leave to get the bus for the plane he was suprised when Lewis pulled him into a tight hug.

"I know you don't believe that I'm your friend, but what I said when we were with Denman was a lie you're like a brother to me. I hope you arrive safely", Lewis said. Ash awkwardly hugged him back wanting to believe his words but unsure if he should. A while later he had boarded the plane and it was about to leave when Denman's voice rang out.

"Wait, don't leave!"

Ash froze in terror, the young man beside him noticed and helped him hide under the seats. It was difficult because of how tight the space was but he managed it. The man had put his things in front of Ash so no one could see him. Ash became more scared the closer Denman came to his seat and had to do a lot to stop himself from panicking and giving himself away when she arrived at his seat. To his immense relief Denman believed the man next to him when he said he hadn't seen him. Ash got up when Denman had left the plane and sat down on the seat.

"What's going on? Why was she after you, you're not a criminal are you?"

"Don't worry I'm not a criminal but I can't tell you the truth I'm sorry. Thank you so much for helping me. I'm As- I mean Aaron".

"No problem, I'm the Doctor pleasure to meet you".

Ash gave him a confused look, "The Doctor can't be your name".

The Doctor pouted, "I prefer it when people say Doctor Who?"

Ash became even more confused, "Seriously what is your real name?"

"I could ask you the same thing. I know it's not Aaron you were about to say a different name".

Ash was saved from answering when the plane started to take off. The Doctor grabbed Ash's hand tightly and used the other too hold the arm rest and squeezed his eyes shut. "Are you okay?" Ash asked in concern.

"Yeah I'm just used to a different way of travelling".

"How come your going by plane?"

"Amy and Rory insisted that I try the human way of travelling-"

"Did you just say the human way of travelling?" Ash said with wide eyes.

"What? No you must be hearing things. Anyway, they said it would be less rocky flying by plane and they lied to me".

"It'll get calm soon, it is only like this when the plane takes off and lands".

"Oh good, I wish they had warned me about this though", The Doctor breathed a sigh of relief when the plane finished take off. They chatted for a lot of the journey making it go faster. Ash was happy to see Stiles waiting for him with his boyfriend Derek. Stiles hugged him with so much force that they fell to the floor.

"Oops sorry about that", Stiles said sheepishly.

Derek helped Stiles and Ash up, "That's okay thank you so much for letting me stay with you".

"No problem", Stiles said happily as Derek hugged Ash. Stiles felt warmth in his heart as his boyfriend hugged Ash, Derek only showed affection to him and Scott and he was so happy he had become friends with Ash. "Come on let's go".

Meanwhile back at Zane's house everyone was freaking out and Emma kept staring at Ash's letter. She cursed herself for leaving him alone for so long but he had been through so much and Emma just thought he needed space.

"I can't believe he did this!" Zane shouted angrily.

"He was just trying to protect us", Emma said sadly, Alec was about to speak but the door bell rang making everyone tense.

"Magnus who is it?" Alec asked knowing Magnus could use his magic to see.

"It's Lewis", Magnus said in confusion.

"What?" Rikki said angrily, "How dare he come here?"

"I'm going to find out why he's here".

"Zane don't it's too dangerous", Magnus said and raised his hand to cast a spell but Zane had already opened the door and punched Lewis so hard he fell to the floor. Zane tried to attack Lewis again but Magnus pulled him off with his magic, he also held Rikki and Emma back from taking their anger out on Lewis.

"Magnus let go Lewis needs to pay!"

Lewis got up, "I know it's hard to believe but I didn't betray you-"

"You hurt Ash!" Emma said furiously.

"I had to make it seem like I betrayed you".

"How do we know you're telling the truth?" Emma protested.

"With magic", Magnus said, Magnus held Lewis in place in case he was lying while he made a truth serum. Cleo continued to stay upstairs as she was unable to face Lewis. When it was ready they questioned Lewis and the potion revealed Lewis was telling the truth. Zane hugged Lewis.

"I'm sorry for punching you".

"It's okay, I'm so sorry for hurting Ash I hope he can forgive me".

Rikki and Emma joined the hug, "It's Ash, it may take a bit of time but he'll forgive you", Emma said. Lewis smiled gratefully at Emma and hoped so badly that she was right he couldn't lose Ash.

Cleo came downstairs after Emma texted her and hugged Lewis tightly making his heart swell with warmth, "I'm sorry I thought you betrayed us".

"I don't blame you that was my plan".

"Have you seen Ash?" Alec asked startling Lewis he had been so lost in Cleo's eyes.

"Yeah I helped him escape Denman at the airport".

"Do you know where he's going?"

"I know he's going to America but not where in America?"

"Magnus do you think you could track him again?" Rikki asked. "We need to get to him before Denman does, it's too dangerous for him to be alone". Magnus nodded and began tracking him.

Meanwhile Denman was back in her office and was trashing it in her anger. She couldn't believe she had fallen for Lewis' trick, she used to be close to Lewis because of their shared love of marine biology. He had used that against her and it made her so angry. Denman had realized something was wrong when Lewis hadn't come back to her after they had lost Ash and when she logged on to her computer to check her computer, she had found that everything she discovered about Ash was gone including the photos she had taken. When Denman had Ash back she was going to make Lewis wish he had never been born for betraying her.

For those who don't know the shows, The Doctor is the main character in Doctor Who. Stiles, Derek and Scott are main characters from Teen Wolf. Stiles and Derek aren't together on the show but I ship them so they are together in this AU.
