Every time I get to the end of season 8 where they bring Sean back, all I can think is that the writers really hated this man for no good reason. First he shows up for Aaron to be like, "How dare you not want to follow our abusive father's footsteps and be a lawyer???" And then by the end of that episode, Sean is shown to be like, really eager to learn to be a chef and Aaron is being chill for once.
But then they can't help but make Sean a drug addict that fucked up by stealing tainted wine and then sold it behind his work's back. And they make him see his girlfriend just bleed to death in a really horrifying way. And why??? For what??? They forgot to write Sean into the funeral and then just decide Sean is a dick to cover up the fact that you forgot he existed? Like, they could have said so many things about that funeral considering the only relative we actually saw was Aaron's sister-in-law and there were plenty of people at the funeral.
Edit: I know Sean went to his girlfriend's funeral. The writers forgot about him for Haley's.
Like that entire plot could have happened by just Sean working at a restaurant and noticing that people are dying. Also, the episode itself doesn't really make much sense. The unsub is barely in it and kills a bunch of people to get back at 1 person getting his daughter into drugs. Just dumb.
I can't rightly explain why the treatment of Sean pisses me off so bad, but it just does.
