Given some of the responses I posted when I first suggested we are closer to the end than we perhaps realise... things like "we have been promised Spring Break" "there's still loads of unresolved things" "But things are just starting with Zoey again" I think there were a couple who were hoping there was going to be something else to resolve in season 4 - I get it, a thing we like is coming to an end, we don't want it too, we think of ways it can continue etc etc
But when you do think about whats left, there isn't much and given DPCs way of bringing most of the mysteries to a resolve in the past if he could end it all at 12 if he wanted too - I'm not saying it would be done in a good manner, but neither would stretching it out beyond its time - the story is unfortunately coming to its natural end and all we can hope now is DPC at least sticks the landing.
the way DPC writes and the way BADIK has gone so far it is possible, and desirable, to end it all now (meaning the plots).
the main storylines have been stretched too far that eventually their closure has brought much more relief than satisfaction. right now, just to stick to the main ones, leaving aside the issues waiting to be squared (I'll give just one example: why Melanie meddles in Sage and Chad's relationship), they remain open:
-James, and here it really only takes a phone call or dialogue to put him behind us
-Jonhatan (Lana), and here again it only takes this conference for the Royces to deal with their grief and it's all over
-Buddy/Vinnie, it depends here, now I don't think that miraculously Quinn's plan has been so successful as to get rid of everyone. but dealing with the survivor should not be a particularly long issue
- the Nerds, their game will be exposed, the fraternities will realize that some of the responsibility is their own and again it will be over quickly.
it is likely to be over quickly because the big questions have been the same since the first season.
all the other issues (Zoey, does the trouple make it or not, the love triangles with
Jil etc...) may very well develop into these long epilogues in season 4.
the spring break would be a great setting for one of the final chapters, i don't see a big problem, DPC loves to create new settings
