The Off Campus Books Already Told Us Everyone's Future, but the Show Changed the Timeline

Major book spoilers ahead.
If you have only watched Off Campus, there is an entire part of these characters' lives you have not met yet.
The fifth book, The Legacy, goes back to Garrett and Hannah, Logan and Grace, Dean and Allie, and Tucker and Sabrina after college. Instead of introducing another couple, it gives the original four their adult chapters. Careers have started, relationships have lasted, and college problems have been replaced by marriage, babies, work and figuring out how to build an actual life together.
There is an elopement, a proposal, a wedding and a surprise pregnancy. Garrett and Hannah eventually have twins. Logan and Grace get married. Dean and Allie get engaged. Tucker and Sabrina are raising Jamie and moving into the next stage of their family.
So if the show keeps going long enough, we already know one possible future for everyone.
The problem is the TV timeline no longer matches the books.
The show has already broken the shared timeline
The Legacy works because the original books keep the main group close enough in age for their adult lives to overlap naturally.
The show has changed those ages on purpose.
Dean is already a senior. Garrett and Logan are juniors. Tucker is only a sophomore. The series is also stretching college across roughly one semester per season.
Tucker is the biggest reason why a direct version of The Legacy becomes difficult.
His love story comes fourth, so making him younger gives the show enough time to keep him at Briar until his season arrives. It solves one problem now, but creates another later. By the time Tucker reaches the same stage of adult life he has in The Legacy, Dean could have been out of college for years.
The show could still use every major event from the book. It would have to stop treating them as events happening on one neat shared clock.
Garrett and Hannah's future may be the easiest one to keep
Garrett and Hannah are in a strong place at the end of their first season, and their Legacy story grows directly from problems the show has already spent time building.
Years after Briar, Garrett is playing professional hockey and Hannah is working in music. Hannah learns she is pregnant but delays telling him. Garrett is also dealing with his father again after years of abuse and pressure.
The pregnancy scares him for a very specific reason. Garrett has spent much of his life terrified of becoming like his father.
The show actually pushed that fear even further.
In the book version of their college story, outside pressure from Garrett's father causes the breakup. The TV version changes the breakup so Garrett ends the relationship himself because he is scared his own anger means he could become the same kind of man.
A future storyline about Garrett becoming a father now fits his TV character extremely well.
The Legacy eventually forces him to face both fears at once. Hannah has a pregnancy scare, Garrett learns he is going to become a parent, and his father is trying to present a false version of their relationship in public.
Garrett finally speaks openly about the abuse instead of protecting his father's image.
By the end, Hannah and Garrett learn they are expecting twins.
Very little about Season 1 closes off that future. If anything, the show has already given Garrett the emotional setup needed for it.
The details could change. The core story still works.
Logan and Grace could reach the same ending through a different route
Logan and Grace have a strange position in the adaptation because their book comes second, while their season no longer does.
Dean and Allie have moved ahead of them.
Grace is still entering the story during Dean and Allie's season, which suggests Logan and Grace can begin developing before they become the central couple. The show already used a similar method with Dean and Allie.
Their Legacy story takes place after Logan has started playing professional hockey while Grace is finishing college. Their schedules have become difficult, they are spending less time together and Logan worries they are slowly drifting apart.
He plans a trip for them. Bad weather leaves them stranded, the trip takes several unexpected turns, and they eventually reach a small inn where they make an impulsive decision to get married.
Later books confirm they stay together and have a daughter.
Nothing the show has done prevents the elopement.
The question is when Logan and Grace will reach it.
Because Grace is being introduced before their own season and the show has already changed the order of the couples, their relationship could end up running through several seasons before the series reaches their adult story.
Their destination can stay the same even if the road there becomes much longer.
Dean and Allie may reach The Legacy sooner than everyone else
Dean has the opposite problem.
He is already the oldest of the main guys, and his romance is moving faster in the adaptation.
Season 1 gave Dean and Allie a relationship before their main season even began. Season 2 now puts them at the centre while Dean is already close to leaving college.
In The Legacy, they have been together for years. Dean is working at a school and coaching. Allie has built an acting career.
Dean decides he is ready to marry her.
Allie loves him, but she is uncomfortable with how quickly marriage can turn into a whole list of expectations about what comes next. Dean prepares a proposal before realising they are thinking about their future at different speeds.
They eventually work through it, and Allie becomes the person who moves the relationship forward. She chooses Dean and proposes on terms she is comfortable with.
Their later story ends with marriage and, eventually, three children.
The show can still reach all of it.
Dean graduating earlier may even make his adult storyline useful while other characters are still at Briar. Instead of disappearing after his season, he could become the first member of the group we regularly see building a post-college life.
His future does not need to wait until everyone else catches up.
Tucker and Sabrina are where the timeline really stops matching
Tucker and Sabrina have the hardest Legacy future to place.
Their original story already moves faster into adulthood than the others because they have Jamie before most of the group is thinking seriously about children.
By The Legacy, Jamie is three. Tucker and Sabrina are getting married, Sabrina has finished school, Tucker has built his business, and they are already making decisions as parents rather than students.
Their honeymoon becomes its own disaster, but the bigger part of their story is about work, family and deciding where they want to build their life next.
The TV version has made Tucker a sophomore specifically so he can remain at Briar long enough for his later season.
That means his adult timeline now starts behind everyone else's.
If the show follows one semester at a time, Tucker cannot easily be married with a three-year-old daughter at the same point Dean has only recently finished his own story. A major time jump could fix it, but a jump large enough for Tucker would also push Garrett, Logan and Dean much further into adulthood.
The cleaner option would be giving each couple their Legacy milestones when the timing works for them.
Dean and Allie could reach engagement first. Garrett and Hannah could move into professional hockey and music. Logan and Grace could get their elopement later. Tucker and Sabrina could reach their wedding after enough time has passed for Jamie to grow up.
Same futures. Different years.
The Legacy may also stop being the final destination
There is another reason the show has room to change the structure.
The world is already expanding beyond the four original romances.
Hunter has entered much earlier and in a completely new way. Characters connected to later stories are being planted before the original four couples have finished theirs. The people making the series have also spoken about wanting to continue into the wider Briar world if the show lasts long enough.
If that happens, The Legacy does not need to become one final season where everybody suddenly jumps forward three years.
Its stories could be spread across several seasons.
Garrett and Hannah can become the older couple figuring out pregnancy and professional life while another romance leads the season. Dean and Allie can deal with engagement while Tucker is still finishing college. Logan and Grace can elope without waiting for every friend to reach the same age.
Then Tucker and Sabrina can finish the original group when their own timeline catches up.
It would fit the structure the show is already using. One couple gets the main romance while everyone else keeps living.
So, are the book endings still possible?
Yes. Most of them are.
Garrett becoming a professional hockey player and having twins with Hannah still fits.
Logan and Grace getting married still fits.
Dean and Allie building careers, getting engaged and eventually having a family still fits.
Tucker and Sabrina raising Jamie, marrying and building their adult life still fits.
What no longer fits cleanly is The Legacy happening in the same way for everyone at once.
The show changed their ages, changed the order of their romances and stretched the college years. Those choices give the writers more time with Briar, but they also mean the fifth book cannot simply be copied at the end.
If the series reaches all four couples, I think The Legacy will work less like one final chapter and more like a collection of future storylines the show can use whenever each character is ready for them.
The fifth book can still tell us where everyone is going.
It just does not tell us when they will get there.
