there are too many plots that will "make sense later" to really hope for it.
let's stay with the relationship between Sage and Quinn: Quinn gets the HOTs to attend the Preps' party, Sage asks her to do one thing: warn the Diks, Quinn doesn't do it, and relations with the DIKs are broken
consequences? i would say none, Sage says she was going to reprimand Quinn, we don't see it, but whatever Sage's tantrum was has no consequence on the relationship between the 2
Sage is sick so she cannot attend the party for the new HOTs, everything goes smoothly except for the 2 girls who were entrusted to Sage and Quinn: one disappears right from the college, the other is the one who from the first moment had relations with Quinn.
this is really strange, but if Quinn says it's all normal then it's all normal
Sage taxitively asks Quinn to go to Maya (the girl who has always had problems with Quinn) to try to convince her to come back to the HOTs. Quinn goes and insults her, tells Sage that Maya does not want to go back in. Sage finds out what happened and blames Quinn's humor, believing Maya anyway or else she would not take her situation to heart.
At the crowning of all these very faint clues Sage gives full power to Quinn to organize the most improtant party of the year and in addition possibly even welcomes her into a threesome with her "boyfriend"
I'm sure that in the next 10 years everything will be explained perfectly
