Stiles definitely wouldnt't be the same old person he was after all that transpired in 3B (and that has yet to happen), so his character is bound for some dramatic change personality wise. Assuming of course he even makes it out alive in the last episode of 3B. If the writers completely ignore all of this and just make him behave in season 4 exactly like he was in previous seasons, that would be completely unrealistic since much less complex and traumatising experiences modify one's character, let alone a freaking possession by a spirit/demon and (bloody) consequences of it.

The other, more direct way (shoving down people's throats) of incorporating said changes to his personality would be to connect nogitsune's departure (exorcism) from his mind with the loss of whole his character including perhaps memories, friendships, feelings etc. So that when he becomes unpossessed, all that is left of old Stiles is practically an empty shell. Then next season, he would have to reestablish connections to almost everybody he knew prior, especially his best friend Scott. That would be interesting writing wise, but, as I said in some other thread, all this emphasis on Stiles' character is kind of an unfair treatment to many other characters/actors who simply are not given their 5 minutes to shine when it comes to the writing/plot.
