So, this is about how Scott doesn’t want to join Derek’s pack and why that’s a smart decision on his part. Not something in his head or something he’s doing to ruin the fun y’all have writing OOC pack cuddles.
To start this off, Scott still does not want to be a werewolf. Has he adjusted to being one? Yes. Has it gotten easier? Obviously. Would he go back to be a scrawny asthmatic who only plays second string on his beloved lacrosse team? Absolutely, in a heartbeat.
Secondly, he has no love or trust of Derek Hale. And he has no reason to love or trust him. Last season, Derek used him to help solve Laura’s murder while stringing him along with as little useful information as possible in order to keep Scott on his side. And the one thing he promised Scott, to let him kill the alpha, he went back on while Scott begged him not to.
At the start of this season we watched Scott watch an innocent wolf get cut in half. And Derek immediately tells him he should become part of Derek’s pack, which will place him directly in the line of fire. Derek tells him the Argents are declaring war. Scott doesn’t want to be involved in a war, he wants to be a teenage boy who plays lacrosse and have a normal high school relationship with the most beautiful girl in the world. Which isn’t unreasonable considering he’s a teenage boy.
And even above that Scott doesn’t consider himself to be a supernatural creature. He sees himself, as you would, as a person who has supernatural abilities. And the Argents don’t. He’s personally experienced Chris Argent pointing a gun at him with the intention of killing him, guilt free, because of Scott’s relationship with Allison. He saw Gerard kill the omega without so much as finding out his name. Chris’ protest about the code seemed weak at best, considering that he’s willing, again, to kill Scott over dating his daughter. That his ‘code’ doesn’t see him losing any sleep over killing an innocent man who was also a werewolf. Because, I repeat, the Argents don’t see them as humans, as people.
Scott also seems to be the first person who sees that Derek is making some terrible decisions. He neither has the bloodthirstiness of Stiles or the vendetta of the Argents, he sees a man who is putting his peers at risk without informing them, which is exactly what is revealed later. And those people leave Derek when they also realize this. The only person who is ruining your pack feels is Derek, who never saw them as his family to begin with.
In conclusion, Scott is ridiculously smart and very good at reading people. And the decisions he makes are very informed and even acknowledged by other people in the show as being the wise choice. Although Derek is unwilling to accept it as he needs Scott more than Scott needs him. Which has always been the case.
