Stiles turned around slowly to face the owner of that voice, though he had no doubt in his mind about who that was. He could've recognized that voice anywhere and probably in the middle of many. Not because he was a special cookie or anything but because he had been making Stiles' life hell since he had shown up in town. It was kind of hard to not memorize the voice of a guy who had asked him to cut off his arm on their fourth meeting.

'Derek.'

He looked at him in the least frightened way he could possibly muster but inside he was screaming and trying to curl into a ball like a hedgehog... if only he had spines, he'd probably be better protected but no, he was just a poor human, probably about to be squashed by the big bad wolf.

'Stiles.'

Something was...different. Derek's voice didn't have that usual underlying menacing tone to it, so his name sounded really weird on his lips but Stiles couldn't really pinpoint what the problem was, he just felt it.

'What do you want?' He said while standing his ground though he glanced at the door and thought about how many steps and seconds it would take for him to get to the door, open it and escape. 'I'll have you know I have Scott's number on speed dial and my dad's downstairs and he has a shotgun.'

Derek smiled... Not the usual smile either, just like it had been with his voice. It wasn't a threatening "I-could-kill-you-right-now-with-my-bare-hands-you're-an-idiot-for-trying" smile but an actual one, rather warm too but all it did was bring a slight shiver to Stile's spine.

'I just wanted to talk to you.' The werewolf said and sounded so sincere that Stiles thought he was telling the truth...for a second.

'You're lying, you can't just have come here to talk to me...you want something, and I know very well you were the one who broke into my locker. What did you want with it? Whatever it is I'm pretty sure I don't have it.' His voice had come out a little shakier than he would've liked but at least he didn't stutter.

Derek simply stood there and looked at him. Stiles did not like that look, not one bit. It was strangely intrusive and it seemed as if he was standing there naked and the werewolf was seeing him completely. 'Say something! Tell me what you wanted or leave, this is my room and my house!'

A mere second later, Stiles was being pinned against the wall behind him, Derek's lips were on his, warmer and tastier than he had ever thought possible, and he was having an internal freakout which made him try to both push the werewolf away and awkwardly kiss him back at the same time. After what seemed like ages, Derek pulled away and a very stunned Stiles was staring at him as if he had never seen him. What. The. Hell. Finally, he reacted and pushed against his chest as hard as he could and even tried to punch him, but derek swerved and avoided it easily.

'What the hell, Derek?' Stiles yelled not even caring that his father might hear him. 'You just kissed me!' It seemed so ridiculous and unbelievably even as he said it that he wondered if he wasn't having a really weird dream... but now, he could still taste Derek on his lips and the warmth of his body pressed against his. The worst part being of course, that he didn't feel totally horrified by it. The memory of himself awkwardly kissing back was way too present.

'I did.' Derek stated in a slightly embarrassed way which was the weirdest thing up until now, counting the kiss. When was the werewolf ever embarrassed about anything? 'Look, Stiles, I didn't mean to do it but you were just standing there, looking at me with those big eyes and I just couldn't resist.' He even rubbed the back of his neck looking all sorry about it and Stiles just wanted to throttle him, slap him and tell him to act normal because it was freaking him out.

'You couldn't...resist?! What does that even mean? Do I have a sign on my forehead saying I'm open for business? No, I do not, so no kissing me with those werewolf lips of yours, because yuck.' It was more of a rant than anything but Stiles was confused enough to not care if he was making much sense. He had even forgotten about the reason Derek was there.

'No you don't...I'm sorry alright?' Derek...saying he was sorry... what was this. 'Look, there's a lot I need to tell you and you're probably not going to believe most of it, or any, but it's all true...and it will explain why I went through your locker and why I'm here now... and most of all, why I kissed you.'

The locker! Stiles really had forgotten about it up until then but everything had basically turned to mush in his head after being pushed against the wall. 'Alright Derek...you better have a really good explanation about this or I swear I'm going to get my dad's shotgun, load it with wolfsbane and shoot it at your face.'

The werewolf sighed softly and sat on Stiles bed looking way too comfortable and he had the urge to hit him with his shoe and shoo him off the bed like people do with dogs, but of course he didn't, he just stood there, in front of him, arms crossed on his chest, waiting to hear Derek's explanation, one he was sure wouldn't satisfy him.

'I was looking for a ring, I thought maybe you might have it...but unfortunately you didn't, because...well because this isn't the right time. It's later and basically, I'm screwed right now...I need that ring and I need it now.' The werewolf told him.

'What sort of ring and why did you think I'd have it? And why are you saying it's the wrong time? What does that even mean? Have you been sniffing mountain ash or something?' Stiles wasn't getting any answers yet and he was increasingly nervous about having Derek in his room.

The tall werewolf sighed and looked at Stiles with a very serious look, one that the teenager was actually already used to which was kind of a relief in a way. 'It's a ring that I'm going to give to you for safe-keeping in the future.' Before Stiles could ask how on earth Derek could know what he was going to do in the future, he continued. 'It's the wrong time because that bastard sent me here on purpose so I couldn't go back. He sent me to a time when there was no ring yet so I couldn't do anything to stop him.'

Stiles just stared in disbelief. This was it then, derek had finally lost his mind. 'What the hell are you trying to say Derek?'

'I'm trying to tell you I need that ring to go back... to you...before he murders you and you're lost to me forever.' the werewolf said, jolting up and towering over him. 'That's why I kissed you, Stiles. I saw you die once... seeing you again was... you have no idea what it made me feel like.'

There was nothing to say then but stare at him and that's exactly what Stiles did. He was frozen in place, trying to make his brain work, but it wasn't obeying him. What the hell was happening here? Derek had gone to his locker, in search of some sort of ring who helped him what...time travel? It was the most insane thing he had ever heard and yet it rang true for one simple reason. He had known that the werewolf seemed different. Still...this meant that he also had to believe that they...got together...dated...in the future. Or maybe it was unrequited or something...yeah that was probably it, Derek was totally pining for him while he didn't give him the time of day.

Except... that was still stupid. Derek wouldn't fall for him...he was just a human that he highly disliked and thought was in the way most of the time. He was one of the reasons Scott hadn't joined his pack after all.

'So what you're saying...' He started. 'Is that we're...' he pointed at himself, then at derek, then back to himself.

'I tell you I came from the future and that's what you ask? Not why you were murdered, or where the ring is, or how it works... you ask if we're really together.' Derek rolled his eyes, looking much more like himself. 'Yes, Stiles, we're together in the future. You and me, me and you.' He chuckled then and made Stiles want to crawl into a hole and hide there forever like a mole. 'I know this is really hard to believe but in a world filled with werewolves and kanima is it really that strange? You're just going to have to trust me and I know it's hard, because I'm guessing in this timeline we're still being idiots to each other, but I need your help. We need to save you and we need everyone's help to do it.'

He wanted to call Derek insane and accuse him of having hit way too many whiskey bottles on the way to his house but somehow he couldn't. It was all completely unbelievable but he seemed so sincere. Still, a Derek from the future? What was this, Doctor Who? Besides, them dating would probably cause the sun to implode or the earth to be sucked into a massive black hole. It just wasn't going to happen. Ever.

'You have these freckles on your butt who look like the ursa minor.' the werewolf stated.

Crap.
