Sterek

Sterek is a slash ship between Stiles Stilinski and Derek Hale from the Teen Wolf fandom.

Canon
They first meet in the pilot episode of Season 1, Wolf Moon, with their last meeting in Season 4 Episode 12, Smoke and Mirrors, until Season 6 Episode 11, Said The Spider to The Fly.

Sterek was first a relationship between two characters who didn't like each other, but as the show progressed, they got over their differences and started having a grudging respect for each other.

Season 1
WOLF MOON "Dude, that was Derek Hale. You remember, right? He's only like a few years older than us."

- Stiles about Derek to Scott

Stiles and Scott are searching for Scott's inhaler, when Stiles suddenly notices Derek standing there. He asks what they're doing there and tells them that they're on Private Property. Stiles apologizes, since they didn't know and Derek tosses Scott is inhaler before leaving. Stiles tells Scott that that was Derek Hale, whose whole family died in a fire a few years ago. Scott wonders what he's doing back, but Stiles doesn't know.

SECOND CHANCE AT FIRST LINE

After Derek is arrested, Stiles sneaks into the police car. He tells Derek that he's not afraid of him, but after Derek gives him a look, Stiles admits that he is. He starts to ask questions about the girl he believes Derek killed and wants to know why she's able to change into a full wolf. Derek asks why Stiles is so worried about him since he should be more worried about Scott transforming on the field. Derek says that he can't stop Scott, but Stiles can and he'll want to. Stiles is then pulled out of the car by his dad.

MAGIC BULLET "Start the car, or I'm gonna rip your throat out...with my teeth."

- Derek to Stiles

Stiles is driving out of the school parking lot, when an injured Derek walks in front of his car. He falls to the ground as Stiles becomes exasperated over Derek being everywhere. Scott then comes up and Stiles hops out of the car so they can check on Derek. Derek says he was shot and Scott asks why he's not healing. Derek says it was with a different kind of bullet and Stiles asks if it was a silver one. Derek calls him an idiot, when his eyes start to switch to his wolf ones. Scott gets Derek into Stiles' car, and Derek tells him to find the bullet that hit him. Scott tells Stiles to get Derek out of there, and Stiles says he hates Scott for this as he drives away.

As they drive, Derek tells Derek not to bleed out on his seats since they're almost to Derek's. Derek says he can't take him there, since he can't protect himself and Stiles pulls to the side of the road. Stiles asks if Derek is dying and Derek says not yet, but he does have a last resort. Stiles angrily asks what he means, but immediately becomes grossed out when Derek shows him the bullet wound. He tells him to start the car, but Stiles says that Derek probably shouldn't be barking orders since he could drag him out of the car very easily right now. Derek just says to start the car or he'll rip Stiles' throat out with his teeth and Stiles does so.

Stiles calls Scott and asks him what he's supposed to do with Derek, especially since he's starting to smell like death. Scott tells him to take him to the vet where he works, and Stiles tells Derek he's not gonna believe where he's tell him to take Derek. Stiles then hands the phone to Derek, who tells Scott to find the bullet.

They arrive at the vet as Stiles gets a text from Scott. He asks if Blue Monkshood means anything to him, and Derek says it's a rare form of wolfsbane. He tells him that he needs the bullet, and Stiles asks why. Derek says that he'll die without it. Stiles drags Derek inside and jokes that Derek's arm will get better with some good night's sleep. Derek says if the infection reaches his heart he'll die and Stiles comments on how positivity isn't in Derek's vocabulary. Derek then tells him his last resort, which is Stile's cutting off his arm, much to Stiles' horror.

Stiles asks what happens if Derek bleeds to death, and Derek says it'll heal if it works. Stiles not sure he can do this, and Dereks asks if he faints at the sight of blood. Stiles says that he doesn't, but the chopped off arm might do it. Derek threatens him again, but Stiles doesn't believe it till Derek grabs him angrily. Stiles then gives in just as Derek starts to puke black fluid. He tells Stiles to do it now, and after some more yelling Stiles grabs the saw. He places it against Derek's arm just as Scott runs in with the bullet, much to his relief.

Scott then hands Derek the bullet, but he passes out. Stiles tries to wake Derek up, but it doesn't seem to be working. He out loud tells Derek not to kill him and punches Derek. This hurts Stiles, but Derek does wake up and is able to use the bullet to save himself. Scott asks if Derek is okay, and Derek says he's fine aside from the agonizing pain. Stiles says sarcasm is a good sign of health, and Derek gives him and annoyed look.
