Arieth as mastermind??
I can´t shake off the feeling that Arieth is not as dumb as she (likes to) appear(s). Okay she fucks them all, but I think it os both literally and metaphorical - for in the end she will be the one on top (again literally and metaphorical). When the others are undone or destroyed themselves in the process she will survive and in the end be the one pulling the strings.
I've been messing around with this idea of Arieth as the mastermind too. I haven't trawled through this thread yet about what other people have theorized in the past so I'll just spew out a few things and people can correct me on them if I'm off base.
How is Arieth still at B&R? I believe it's mentioned, maybe by Tommy, that Arieth was one of the 'rejects'. This explains how she entered the college. But it's also mentioned on Rooster (I think by Quinn) that Arieth is still taking first year classes. If Arieth is just pretending to be dumb, that's a very long con, but more importantly who is paying for that? Does Arieth have rich family, is she just stupidly accumulating debt, or is she involved with Burke and his free tuition scheme? I think it's most likely that she's working with Burke, as it's already been established that he likes to bang his students and is willing to fabricate free tuition to achieve that, so given Arieth's willingness to bang anyone they seem to be a match made in heaven. If that is the case, Arieth could be Burke's spy on the DIKs, the HOTs and the jocks, seeing as she's the only person we know who hangs around every group regularly.
Another thing that I thought of was the fact that the jocks attacked the DIK mansion with dildos. I don't think it's ever resolved as to why they had so many dildos, but my guess would be that they got them from Arieth. Who else would have so many just laying around? However, it's never mentioned by anyone that they belonged to Arieth, and Arieth never tries to get any of them back, so this makes me feel that I may have missed something obvious about where they came from in the game. It's just suspicious that the jocks could have shown up with anything to attack the DIK mansion, they're a bunch of athletes so they must have plenty of balls and shit, but they chose to show up with dildos. That may be significant, may not - if it is significant, it could point to Arieth intentionally sleeping with Tommy to start the beef with the jocks, then leaving the dildos conveniently for the jocks to use to attack the mansion. Why? If she's working for/with Burke, he may want them fighting for some reason, I haven't thought that far ahead yet.
It seems to be that Quinn is the one pointing out how Arieth is especially dumb - she does this on Rooster about how Arieth is still taking first year classes. Also, Arieth eats the dog food in front of Quinn, although it's been debated as to whether Quinn noticed that detail since she was high at the time. So the two dumbest things about Arieth we know from Quinn. If Arieth is Burke's sleeper agent, is she there to spy on Quinn for him since Quinn is also working for Burke with the prostitution stuff?
There are a bunch of other smaller stuff I won't get into. Why the devil's threesome with Arieth and the two DIKs was filmed from a top corner of the room. The times Arieth has taken swipes at people on Rooster - especially that one time when she pretty nastily went after Riona on Rooster and then backtracked hard when people defended her. That's pretty suspicious to me because no one else in the entire game says anything bad about Riona except for Arieth, and now that Riona has a stalker there might be some connection there somewhere... maybe to do with Anthony, who I also have suspicions about.
