In reading part of your suggestions for Ophiuchus' state of the game, I was surprised one of the ideas you requested was a more inclusive event. You stated that some characters (I'm assuming you meant your own) weren't interested in expeditions/exploring, but I feel like Stiles as a character contradicts that claim completely. Teen Wolf begins because Stiles grabs Scott and drags him to the woods. He's nosy, he gets into everybody's business and you had Stiles mope around for months.

While, yes, coming back from an update from the events of 3B would effect Stiles, I would never go so far as to say he'd hole up in his hut alone and simply mope. This season has proven that. He's going throughout his day, moving forward and being a great influence on Malia. You hardly have him interact with his own cast. Despite Isaac not being his favorite person, I'd hardly think he'd shy away from everyone including the only people he knows from home. Yes, Scott is gone but Scott wouldn't want Stiles to sit around moping and he knows that.

While Allison dying is a huge deal, I don't think he'd ever stay away indefinitely. Even for Scott's sake, he'd look out for the love of his best bro's life.

I think you're getting better at putting him out there, but his attitude is hardly what I'd call Stiles.

My suggestions are to reincorporate him into his own cast, talking to other people besides Rachel, and to go on a freaking expedition. Because he would.
