Thad, David, and Wes look like friends or at least on good terms but I have secret intel (headcanons, I made all of this up) that in season 2 when Thad and David are sophomores and Wes is a senior, Thad and David got involved in pretty useless drama the year prior. Wes was their only mutual friend and he kinda checked out for his last year of high school.
You see, in freshman year, David and Thad were both new and pretty good. Good enough to land a spot on the council, but who should get it? Only one spot will be open next year. So the two engage in show choir rivalry, the likes of which would make Rachel and Mercedes proud. They have to really tone down the competitiveness when Wes chastises them for unsportsmanlike conduct towards their own team members. And then, after eight months and a very very close call decision, David makes it and Thad doesn’t.
Except, one of the council members transfers to a different school. So there is a need for another new council member. And who else but Thad should get it? And yeah, he does get what he wanted. But he still can’t shake the feeling that he wasn’t their first choice.
During Season 2, he has to work with the guy who was ever so slightly better than him. And also his responsible friend Wes. Thad tries his best to make the most responsible council decisions possible, sometimes he just happens to clash with David. Council only meetings often end up in disaster, leaving Wes to handle a lot more of the responsibilities than he would like.
So he forced the two to make up or at least be civil when they work on Warblers council shit, so they begrudgingly comply until the very end of the year when they realize they actually really do enjoy each others’ company. Then at Wes’s graduation, they are very miserable because more than half of the last two years was wasted on petty bullshit and now one of their best friends is leaving.
So Thad and David become actual friends come Junior year (s3), which is also conveniently the time they need a new council member. It would’ve been Blaine, but he left for McKinley. Who do they pick?
The answer strides through the door with the confidence of a seasoned sous chef entering a restaurant’s kitchen. Sebastian Smythe, in all his arrogance, can sing quite well. And he has the charisma that, somehow, draws most of the Warblers to him. And so he replaces Wes as third council member.
Now, David and Thad are pretty good leaders, don’t get them wrong. It’s just that Sebastian’s leadership style is a lot more… independent. But as private school college counseling gets a lot more time consuming, it’s probably best to let Sebastian take care of the day to day rehearsal work while Thad and David plan competition technicalities.
The events of On My Way definitely change Sebastian. While he’s still a little bit bossy and continues to lead practices, he’s also more involved in behind-the-scenes stuff. David and Thad are definitely warming up to him.
Suddenly, senior year rolls around and the school brings on Hunter to lead the club? Do schools even recruit for show choir?? It’s the pair’s last year though, and no one is keen on losing either senior as a leader if Hunter also has to have power. So they have to kick Sebastian off.
In the timeline where Hunter doesn’t use steroids for a singing competition, maybe the trio forms a short lived bond. They have a really awesome graduation party where Sebastian triple checks with all the returning Warblers that he will most certainly get to spend his senior year as an actual council member. They’ll actually reinstate the system, gavel and everything. David and Thad cheer, because Wes really liked the gavel.
