Sterek

"Don't be such a sourwolf."

- Stiles Stilinski

Sterek is a slash ship between Stiles Stilinski and Derek Hale on MTV's show Teen Wolf.

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.

Episode 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 Derek first meet in this episode. Stiles is wondering around with his best friend Scott in search of Scott's inhaler that he had lost the previous night. They end up finding Derek, who demands that they get out, as this was 'private property', before tossing Scott his inhaler and walking away. Stiles mentions that he knows Derek, as Derek was only a few years older than them, before he had left school.

Episode 2: Second Chance at First Line
"Just so you know I'm not afraid of you. Okay maybe I am."

- Stiles to Derek in the police car

Stiles and Scott go to Derek's house and discover that he has buried half of a dead girl's body beside the house. Stiles and Scott end up getting Derek arrested. While Derek sits in the sheriff's car, Stiles gets in and starts off by saying he isn't afraid of Derek...ok. Maybe he is. They end up having a very tense conversation, before Stiles is pulled out of the car by the Sheriff, leaving Derek behind in the car.

Episode 4: Magic Pullet
"Start the car, or I'm gonna rip your throat out...with my teeth."

- Derek to Stiles

Derek goes to the high school after getting shot by Kate Argent, while in the parking lot Stiles almost hit's him with his Jeep, before he ends up passing out. Scott and Stiles get Derek into the car, driving to the animal clinic for safety while Scott goes to Allison's house to find the substance used in the bullet that shot him. When the car is stopped for a short while Derek tries to explain how the bullet will cure him but if Scott doesn't get it in time, he has a last resort. Stiles becomes confused, but then extremely grossed out when looking at Derek's wound. Derek then orders Stiles to keep going, but Stiles banters back how he could probably drag him out of the car if he wanted. Derek responds by threatening to rip his throat out. The two arrive at the animal clinic, Stiles dragging Derek. Thinking that he's run out of time Derek takes a tie, cutting off the circulation is his arms to above the infected area of his arm. He then hands Stiles a saw and tells him to cut it off. Luckily Scott arrives before they can. Derek then faints. Stiles then attempts to wake him up, first by shaking him, then by punching him, which hurts his own hand, but does work. Derek then heals himself while Stiles cheers at how awesome that was.
