DPC don't make you believe in anything. He just showed you blatantly who are behind the most shit in the game universe or B&R part in particular. Only small and not that important details are leaved behind for now - like who installed the cam/s, who nerds asked/hired for it, who helped to get access to laptop or how it happened, etc - "underlings". Now you can go like on me again with "you can't read into things"... but... in your so beloved Q/A DPC mentioned that we reached the line where more questions going to be answered and only a few new are being asked. So, he literally said that he will bringing more and more answers rather than raising new questions. Things will become simpler and clearer with each new episode, not the other way round.
DPC showed the Betas motives, and how long they planned and prepared for it - "for years".
Arieth is dumb as a rock, literally. Her new role as a sex-toys salesman is more comical than realistic. But that's her ceiling. Don't involve the poor stupid girl in the war and the nerd rebellion.
Those pics from laptop, obviously. But why you make Arieth responsible for stealing Jamie's phone? Just how this is connected? The only thing we know - he mentioned to Tommy that he lost his phone recently. Ok, Jamie thinks he lost it, probably it's true, then someone, maybe one of nerds find it and gave to Magnar. Or it was stealed during party or somewhere in college. It's useless to make assumptions because we have zero hints of how/when/where Jamie lost his phone.
Regarding Sally - maybe she was used in some tasks previously, while we know she was one of those nerd girls who attended HOT's and DIKs parties. Then it's the question, did Betas banned her for real after around EP8 or it's just a bait for MC. We see her upset and single during dorm party in EP 8, while Magnar sits in his room and seems annoyed that Ron is partying and not studying more. Same probably goed for Sally. But Ron is vice-president and Sally is Sally...
He says that Betas revenge and good times for Betas are coming. You say/do so when you "protect" something? Revenge/provoking fights between all major frats, so they dissapears and only Betas remain sounds like "protecting" the frat? Why you can't read/understand what characters say? Both Magnar and Ron, btw.
Arieth & Dawe are mostly comical characters, as well as their "relationship". The dude denies reality and pretends not to notice that she sleeps with half of the college, but gets furious because of the photos of her sleeping with someone, in particular with the DIKs. Dawe is classic idiot and so her "girlfriend". They are so worth each other. Anthony and Chad are the most adequate ones among the jocks.
Magnar knows what MC & Chad talked about (or just noticed how uncommon their talk was, which is more realistic), as well as he knows about Chad secret and even have a photo of Chad & Troy in the locker room. He realised the "plan A" with his letter already and says about switching to plan B in case if "A" will not work out and Chad won't get a bait (he won't, because he talked to MC and knows that someone framing them). Plan A haven't worked out as WE, players, know, so we will see what's the plan B was about in the future episode.
I don't wanna to comment J&M part, bc it's so over far fetched.
Caleb settled in and started pumping and demanding rights and breaking through to the top of the food chain. Despite the fact that other jocks respect Chad, at the moment he is practically without rights, even though he regained the title of president. So he defiantly gets into an argument with Chad when he picks up the letters. Caleb presents it as a struggle for justice. And at the same time, he notices that Chad has something to hide, although initially Caleb assumed that the letter could contain something about Sage. So here Chad and Troy situation worked out better than Magnar could have imagined - the conflict within the Alphas is embedded and will continue to develop. Caleb will "dig" for Chad, etc.

How all this is connected? What Tybals letter is about then? There're so much more interesting things to blackmail/instigate/fool with Tybalt for...
Tybalt thinks too highly of himself to go to a college locker room. He has his own equipment, a racket, and so on. And he probably doesn't keep it all in the locker room. More likely in his own room or in the mansion's closet.
At that time, Tybalt barely knows MC, who he is, etc., what's the point of him framing a random dude and doing it in such a confusing way? All he's interested in about is: Jill, Dad's money and position in college and his own ANO fraternity. As always, you complicate everything many times and adjust the behavior of the characters to your theories. Instead of looking at things more realistically and building theories based on what the characters are like, how they behave, and their personalities... based on all this, and what can be expected from them. i.e. You're saying that Tybalt told Chad about MC (whom he doesn't even really know), that he was the one blackmailing him. But how the hell did Tybalt knew that someone was blackmailing Chad? They're friends who spend a lot of time together, and while drinking some beer together?... Chad is like, "Tybalt, someone's blackmailing me," "Oh, I know who it might be - MC.".. That's what your theories look like.

DPC consistently, persistently and quite predictably unravels the tangle of his "riddles" in all recent episodes. Everything is more than predictable, logical, without kinks and without using characters out of their and for other purposes (as it usually happenes in your global conspiracy theories). Sometimes plot twists happens unexpectedly and unpredictably, but... without too much fiction, mysticism, time jumps, spy kids and other nonsense. And more and more realistic theories or assumptions are being worked out, especially if they were based on a healthy analysis rather than coming up with something that doesn't exist or ever existed. Sometimes something is veiled or the words of the characters should not be taken literally, because they mean something else or just lie, but you shouldn't see a double or triple bottom under EVERYTHING and EVERYWHERE. Everything in this game is much simpler both in terms of the story telling and the plot. It's a pity that you keep generating completely unrealistic theories that run counter to what has been shown and revealed in recent episodes. It remains to reveal just a couple of important details and secrets, and everything else will follow. But you're still generating such a theories, that's like as we are having 25+ episodes and 5-6 seasons at least.
