A/N:My take on how Stiles will react on finding out that Derek is alive. Spoilers for episode 5, and possibly episode 6 if you haven't watched the previews yet.
Warnings: Angst, one-sided Sterek, Dennifer/Jenerek. And made up stuff about the Darach and human sacrifices.
Stiles was relieved when he had found out that Derek was alive. It hadn't really been surprising as much as worrying for Stiles, since he saw the man be stabbed in the back with claws then thrown against a brick wall by his crazy homicidal uncle and still managed to survive unscathed. Nevertheless, Stiles still worried since just thinking that there was a possibility that Derek really did die made Stiles uncomfortable, because Derek can't die.
They were currently on their way back to Beacon Hills, and everyone was still recovering from the shit storm that happened back at the motel. It turns out that the motel owner was actually a witch and put a spell on her tenants to hallucinate their biggest fears, causing the victims of the spell to commit suicide. Some of them were actually close to taking their own life, before Lydia managed to stop the witch- since she was immune to the spell, just like how she was immune to anything supernatural.
Their triumph over the witch tasted even sweeter when Scott got a text from Ms. Blake informing them that Derek was indeed alive. Stiles' immediate reaction was to be relieved and happy to know that Derek was alive and that someone was taking care of him, then surprised that Ms. Blake was apparently in the know about the supernatural and that Derek trusted her enough to take care of him. Stiles brushed off the feeling that he was being left out of the loop again, not letting anything ruin his good mood
As soon as they reached Beacon Hills, the group split up and headed to their respective homes to lick their wounds, whether it be emotional, psychological, or physical, all except for Stiles whose main priority was to check up on Derek, probably annoy him for a bit (just to check if Derek was well enough to be annoyed at him), and definitely ask what happened and how he managed to survive.
Stiles arrived at Derek's loft and the first thing he noticed was the lack of light seeping out from beneath the metal door. Derek probably was sleeping, trying to rest in order to heal as quickly as possible. Stiles should have walked away then, but he wanted to see for himself that Derek was alive- that Derek didn't actually leave him.
He opened the door as quietly as possible. The loft was dark, but he still managed to see, since the moonlight illuminated most of the open space. Stiles took comfort that the loft seemed to be intact, meaning that no one tried to go after Derek in his weakened state. He tiptoed his way to Derek's bed, but nearly tripped on someone's high heels. Stiles frowned as he saw Derek and someone else's clothes strewn about the floor. Stiles closed his eyes before finally looking at Derek's bed. Stiles felt numb at what he saw. Derek had an arm wrapped protectively around Ms. Blake, the two of them chest to chest and fast asleep. Stiles quietly slipped away, trying his best to hold back the tears that were forming in his eyes. It was only when he was in the safety of his jeep that he had let them fall.
Stiles was an idiot for not seeing this coming. Sure, he didn't expect Derek to reciprocate his feelings, but at least Stiles used to have the option to believe that he might actually have a chance. What hurts the most was not that he'd seen them that way, it was the small smile on Derek's face as he slept and knowing that Stiles would never be the one to make Derek smile that way.
Stiles let his instincts take over as he drove aimlessly. He didn't really care where he ended up. All he knew was that he needed to get away. He wasn't really surprised when he found him staring at the entrance of the graveyard. Stiles grabbed his flashlight and made his way to his mother's grave. He sat beside her grave and babbled on and on about Derek. Stiles thought that that would get Derek out of his system. He was wrong.
Stiles had turned off his phone at around three in the morning, when Scott and his dad started calling and texting him, all of which he ignored. He spent the rest of the night thinking and wondering how to get past all of this. And as always, his hyperactive brain did not fail him.
Stiles hopped on the elevator, hoping that he would not bump into Allison or Mr. Argent. He could feel his heartbeat thump and beat erratically, as if it somehow knew what Stiles was about to do and tried to warn him not to.
He tried not to think about his dad and what his reaction would be a t the note that Stiles left that explained everything. He tried not to think about Scott and how he would slowly turn to Isaac for friendship, not that it was already happening. He tried not to think about Lydia who still needed help in figuring out what was happening to her. And he definitely tried not to think about Derek and what his reaction would be when he found out.
Stiles took a deep breath and knocked on the door. It was Deucalion who answered the door. "Mr. Stilinski, what an interesting turn of events. How may we be of assistance?" Stiles masked his face into indifference and spoke calmly. "I know about you and the Darach. I come as a willing sacrifice, the most potent sacrifice of all, if you promise to leave everyone alone." Deucalion gives a predatory smile as a response. "Do we have a deal?" Stiles asked, as he stretched his arms. Deucalion grabbed his hand and shook it. "Deal."
