I don’t trust Stiles.
Because he is the one character the writers want us to trust.
They have been emphasizing and reiterating and referencing all these reasons why Stiles should be trusted as a narrative tool - his isn’t being messed with mentally, he’s had no contact with the Alpha pack that fucks with memories (all the werewolves), he isn’t hallucinating (Allison), he isn’t losing time (Lydia). Every other character is having these things happen or are otherwise shrouded in mystery (i.e. Deaton and Morell).
But not Stiles.
Not only that, but he’s become obviously and dramatically the head of all things “information.” From the bank research to dealing with the Darach and all its lore - Stiles is the one in charge. They keep making references to how he’s always been right before (see above) and gave us a list of 4 suspects that we are supposed to be working off of - Harris, Cora, Deaton and Lydia.
And that last gif is basically a flashing sign of “No one listened to me before when I was right so you should all listen to me now!”
Which is exactly why I don’t trust him.
The writers want us to trust him. They’ve made that glaringly obvious. All of the other teenagers are being messed with and all of the adults - including Derek - have elements of missing information or otherwise shadiness that tell us we can’t trust everything we know or that we think we know.
Except with Stiles.
Not to mention that he was alone in Derek’s loft with Peter Hale, who is just as shady-as-fuck this season as he’s always been - and given Stiles first reaction to Lydia losing time, it’s incredibly suspicious that Peter isn’t on his list. He’s also the most vulnerable out of all of them, as the human without immunity or intense training. Of course being the Sheriff’s son that is also in the know puts a giant target on his back.
This is not at all to say I think he’s the mastermind behind everything - or anything really. I think he’s just as much a pawn in this situation as the rest of them. Either he’s being controlled or his memories are being altered or something.
And I’ll say it again, Jeff’s favorite thing to do is wave his right hand loudly and obnoxiously over there while pulling off the season twist with his left. What we see is never what we get and there’s always a subplot that is really the most important one.
And another thing - it’s always someone we know. We always meet all of the players early on in the season - Peter and Kate and Matt and Gerard…. and Lydia and Jackson and even Scott who have pulled off subplots all on their own.
EDIT: OKAY WOW. Just to clarify, I do. not. mean. that Stiles is pulling off the murders intentionally. At all. I think he cannot be trusted as a narrative tool - meaning they want us to believe everything he says and work off his theories - they want to throw us off.
Also, wouldn’t be just like Jeff though? For Stiles to be unaware that he’s doing it? or helping? Because they’re telling the whole plotline of figuring out who it is FROM his perspective. We’re supposed to go to him for guidance, as the viewer. Kind of like Derek going to Peter in season 1 for help figuring out who the Alpha is…
