Another Reason That Would Have Thwarted Theo’s Plan: Scott Wouldn’t Have Been So Smitten With Theo

Another reason that would have thwarted Theo’s plan: Scott wouldn’t have been so smitten with Theo if Isaac was around. That’s a bond that would be harder to break. Isaac wouldn’t turn away from Scott for anything, and he didn’t have anyone else to go to if he was even thinking about it. Would be interesting to see Theo working on it, but even if Theo managed to convince Isaac that he’d seduced Scott into cheating on him, I think Isaac would stay loyal. And as long as Scott had Isaac, he wouldn’t get to a point where he felt like Theo was the only one he could count on.

NPFP made me wonder something: what do you think would have happened had Jackson and Isaac been around for season 5?

I'm pretty sure Theo wouldn't have succeeded. Sure, Theo would've most likely wrapped Scott around his little finger because Scott is a moron when it comes to trusting strangers, but Stiles would've never been alienated from the pack because Isaac and Jackson wouldn't trust Theo over Stiles — mostly because they have common sense and are aware that you do not trust people, who you just met and who record your girlfriend sleeping, over your best friend. They provably also wouldn't have cared that Stiles killed someone.

After Ethan and Aiden and Peter and Matt, and Allison going rogue, Isaac would've rather eaten his scarf before trusting the new random werewolf that showed up the second shit got weird.

And Jackson? I mean, he spent weeks listening to Stiles babbling on and on about how weird Matt is. He also spent a lot of time with Stiles in a van, telling him exactly what he is. Plus, Lydia is Stiles' best friend, so there's that too.

But yeah, I don't think Theo would've been able to accomplish anything.
