This may or may not be the last chapter. In fact it is the last chapter. But I have another plan in the back of my head.

Disclaimer: I don't own Teen Wolf or Stiles or Derek.

Special thanks to all my reviewers.

Stiles was seated at the kitchen counter when Derek got home. The lycan set his keys down on the kitchen counter along with the empty packet of cigarettes and his lighter. Derek pulled up a stool and sat across from the teen, eyes focusing on the granite counter. He didn't acknowledge the teen. The conversation he had with Scott replayed in his head.

"Derek, look, I think you should give him a chance," the young werewolf said.

"What do you mean, he fucking went behind my back."

"Derek, give him a chance to explain himself, at least let him try to-"

"No."

"Derek, look I know you, I know you well enough to know that no matter how much he hurt you, some part in you wants to listen to him, wants him to be the one that makes it go away."

Derek sighed. "Yeah but the other part, wants me to run away."

Scott stood up. "Okay fine, throw away your relationship that you've been working on for nearly a year now."

Derek growled, his eyes flashing blue. "Don't you dare pin this on me Scott, Stiles was the one that went behind my back!"

Scott's eyes flashed gold, "I'm not pinning it on your, nor am I going to pin this on Stiles but are you going to be that big of an idiot-"

Scott couldn't finish his sentence; Derek had tackled him to the ground. Both were now in their wolf forms as they wrestled and growled at each other. Derek didn't know how it happened but Scott had him pinned to the ground "Derek, hear me out!" he growled.

"Get off," Derek growled.

"No, Derek you listen to me, you need to let Stiles explain himself at least. Yes I know he did something stupid but you'll be making a mistake too if you don't at least hear what he has to say."

"Fine, I'll hear what he has to say."

Derek slid the empty packet towards the teen "I didn't smoke any," the lycan said.

Stiles eyed the empty packet, "But the packets empty."

"Oh I know, I wanted too, but I couldn't, they're in a pile on the park floor"

Stiles nodded.

"Want to know why, I couldn't do it?" Derek asked, finally looking up, his eyes locking with Stiles'.

"Why?"

"The whole entire time I kept on thinking about how much pain it would cause you if I smoked one, how disappointed you'd be if I lit one, how upset you'd be if inhaled the smoke."

"I-I-I'm glad you didn't, you scared me for a minute."

Derek nodded. "But you know another part wanted me too."

Stiles breathing hitched. "Well…I'm glad you chose to ignore that."

"Why'd you do it Stiles?" Derek asked his tone serious but laced with pain.

"I don't know."

"So you're telling me, this thing with Danny," Derek growled speaking the other's teen name as if it was poison, "you did it because you don't know!"

By now Derek's voice had escalated and he stood up, the stool landing on the ground with a thud. Stiles jumped and winced at the loud noise as tears threatened to fall from his eyes. And that's when Derek could feel it, Stiles was lying. Fear was rolling off of the teen along with guilt and nervousness. "Stiles, you tell me right now or I'm walking out on you and I put that on everything in fact I put that on Laura."

Stiles looked up. Laura was family and Derek was devastated at the loss of someone so close to him, someone who was there for him. Stiles knew that because the werewolf had told him. And Stiles also knew that if Derek put anything on Laura, he was dead serious. Stiles took a deep breathe. "The first time it happened it was an accident," the teen breathed.

"Jesus Stiles," Derek whimpered, "so you mean the rest wasn't."

"The second time, I..well it-it just happened, I don't know how but it did, we were arguing over something stupid and before I knew it, he was kissing me and well…I was kissing him back."

"And it didn't register in your brain that you were with me!" Derek cried out.

Stiles didn't say anything which caused Derek to slam his fist down on the granite counter. A loud crack resonated off of the walls causing Stiles to jump. Derek was fighting back tears. "What happened the third time?" the lycan forced out.

Stiles breathed in deeply. "I-I initiated this one."

That's when Derek lost his composure and his ability to think straight, well it was tossed out the window. The stool on the floor flew past Stiles and hit the wall behind him breaking into pieces. "God damn it, WHY!"

"I wasn't thinking!" Stiles cried out.

"Well you clearly weren't thinking about me!" Derek roared "I mean jeez, did you just forget I existed or something!"

"No! Derek of course not."

"I must not be that important!" Derek cried, "For you to kiss him and forget that you were with me at the time."

"But Derek-"

"We're done," Derek chocked out "I can't be with you Stiles, I can't."

"But Derek, it didn't mean anything."

"That is complete bull shit Stiles," Derek growled, "if it didn't mean anything then why did you do it."

"Too see if it did, too see if there was something there."

"Is there?"

Stiles shook his head. "No!" he cried out "Nothing, Derek, you're the one that I love, you're the one I want to be with"

The werewolf shut his eyes and ran his hands over his face, willing the tears to go away. "If you loved me you wouldn't have done what you did."

"Derek-"

"You can stay the night, I'll let you sleep in the bedroom and I'll sleep on the couch," Derek breathed "and in the morning I'm calling Scott, he's going to come and get you."

"No," Stiles whimpered.

"Yes and after that, well I don't want to see you."

"Derek, please."

"I don't want anything to do with you."

Stiles whimpered, "You don't mean that do you?"

"Stiles, I need time to get over you."

"Will you ever forgive me, give me a second chance?" the teen breathed.

Derek made a fist, tears also falling from his eyes, "Over time I'll be able to forgive you but Stiles, no, you lost your chance."

"Der," Stiles whispered "I'm sorry."

"Still can't call me that," Derek whispered.

"I love you Derek," Stiles whimpered.

Derek walked over to Stiles placed a kiss on the teen's forehead. "Goodbye Stiles."
