Fly a Little Faster by  mirrorkill | 32K
Everyone knows when you go back in time, you shouldnât step on an ant, just in case you accidentally kill your own grandparent or something. But what happens when you go back in time and, uh, accidentally interrupt the one event that apparently made the Grumpiest Alpha in Town into a ball of mindless manpain?
Well, if Marty McFly can do it, so can Stiles Stilinski. All he has to do is get Derek and Paige to fall in love before he gets pulled back to his own time. And before he makes anything worse. Thatâs easy as pie, right? Right?
Where Clouds Roll By by  ohanotherday | 22K
Derek gets de-aged, physically *and* mentally, and immediately gravitates towards Stiles instead of his pack. Why? Because he can sense that everyone else (Scott, Erica, Boyd, Isaac, etc.) is a werewolf (or were-something, in Jacksonâs case), and his family taught him not to trust unfamiliar weres when he was on his own. He can also sense that Allisonâs a Hunter or connected to them somehow, (maybe she smells like wolfsbane? w/e). So Stiles ends up having to take care of him until heâs back to normal. In the meantime, bb!Derek gets very protective of Stiles, and adorable shenanigans ensue.
This Time With Feeling by  Crimson1 | 36.1K
âDerek Hale, if you refuse to learn from your pastâŠthen you will be doomed to repeat it.â In which Derek is turned into a 16-year-old and has to stay with Stiles until they figure out how to turn him back.
Play It Again by  metisket | 63.2K
In which Stiles goes along with one of Derekâs plans and ends up in an alternate universe as a result. He shouldâve known better. He did know better, actually, and that means he has no one to blame but himself.
âLaura wants to lure the kid in with food and kindness and make a pet of him, like a feral cat. Derek wants to have him arrested for stalking. Theyâre at an impasse. (And the rest of the family is staying emphatically out of it in a way that suggests bets have been placed.)â
Where The Inevitable Isnât by  Survivah | 41.2K
Stiles has a magical thingamajig thatâs supposed to get him out of danger. Trouble is, it took him really, really far out of danger. Like, to the point where he isnât in the same universe anymore.
âA part of Stiles had been thinking that heâd come home, and just go, âhey, Derek, are we mates and you just havenât said anything about it?â and Derek would reply, 'now you mention it, we are indeed! Now come to my bedchamber, where we will have super hot sex and then cuddle after!ââ
Now as Ever (All That Is and Has Been) by  venis_envy | 52.2K
Stiles canât remember what happened to rearrange the time-space continuum, or how he ended up being pulled into the past. All he knows is that heâs there now, in 2003 Beacon Hills, with a teenage werewolf and a possibly-crazy veterinarian as his only allies.
Hormonally Yours by Nokomis | 1.1K
Stiles is on a stakeout with adorably teenaged Derek. Makeouts happen.
A Wrinkle in Time by PencilTrash | 2.8K
âBut Deaton, how do we change him back?â
âI donât know, Scott.â
âDoes this potion contain wolfs bane?â
âA little.â
âWhat?! But he's⊠he is⊠â Stiles watched as Scott struggled for the correct word, totally freaking out, and gestured at the twitching blanket in Coraâs hold. â⊠so small,â Scott murmured after a beat.
Iâll be right back (in 24 years)Â by AnaIsFangirling (Ana_K_Lee) | 48.1K
When Derek thought about time travel â and he did, a lot â this was not what heâd had in mind. Heâd thought he would see his younger self, tell him to leave Paige alone and NEVER trust Kate Argent. Heâd thought heâd get to come back once that was done and everything would be perfect. He never imagined having to relive his entire life.
The Time Travelerâs Prerogative by  weathervaanes | 9.2K
After the events of â117â, Derek doesnât magically transform back into his twenty-five-year-old body. Instead, heâs stuck as a sixteen-year-old for an unknown amount of time. So the pack has to learn to deal with it.
Hold On, Hold Tight (make it through another night) by  callunavulgari | 2.9K
âYou feel important,â Derek finally blurts out, the tips of his ears going red the second the words are out of his mouth.
Stiles blinks at him. âWhat?â
Baby-faced Derek bites his lip again, which is⊠distracting. âSomething is wrong,â he finally says, slowly. âI donât know what, because none of you are telling me anythingââ and ah, thereâs a hint of the old Derek. Stiles would recognize that scowl anywhere. ââbut I know that everything smells wrong. And that I canât feel mom anymore. I canât feel anyone, except for you.â
