What influence AAAs lost? Their president was replaced, nothing happened at all.
DIKs lost the place for parties and yes, they was off the game for a couple of months. Yes, somebody obviously hate them for their best parties and want them to go down.
All the bullshit theories about BBBs, Vinny, being the ones, who trashed their mansion, etc were gone to the trash after EP10.
So the AAAs was the ones who made a revenge on DIKs and put them off the game for months. But the AAAs were provoked to do that in some way. But if DIKs wouldn't trash AAAs mansion with dildos then DIKs mansion wouldn't get trashed too. So, don't far fetching this. Partially it was a Quinn fault, as well.
The jocks are forced to behave carefully, not to get into fights or provoke anyone since they are under surveillance.
In short, the tracks lead back to AAAs. They have the motivation to hate DIKs and shit on them in every possible way one way or another. They agreed to Sage and Quinn's terms, but continued to shit behind their backs. Well, except that they refused direct physical actions by putting a jacket on Caleb.
So, AAAs knowing and able to use some person (girl) that could act as a rat is the most plausible explanation at the moment.
They're dumb as corks. None of these guys can solve a simple math equation without a calculator. The only thing they're interested in is competition, and they'll do anything to win it. They can't organize an operation this complicated just to hurt Deeks. They always operate in the open and don't even hide it. If they were really involved, there would be hints in the game, but there aren't.
There are hints in the game that the girls from the dormitory are involved and there are many of them.
Becky and her friends were the ones who benefited the most after temporarily neutralizing DIKs.
I think their original plan was just to start another war. But when that plan didn't work because of Chad's ouster, they just hit them directly. Now that DIKs are back on track after the first party, they've struck again.
I don't know who could be behind this.
It could be a traitor among DIKs who secretly hates the brotherhood and wants to destroy it.
