We get more flashbacks and scenes of the core four
Serena and Dan do not end up together
Serena and Nate end up together or at least are a couple longer or at least more of their friendship
More of Serena and Chuck's friendship after becoming step-siblings
They should have waited longer in between everyone, especially the core 4 dating each other
Blair and Dan never happen, and Blair is not the star of Dan's book
Nate and Blair freindship post season 2
More, Lily and Chuck's mother-son dynamic
Serena never dates Steven, and Nate never dates Sage
Dan should have been left out of the group in the end. Especially how he acted in season 6. It also makes sense for his ending to be Gossip Girl. It would have been such a good narrative of him being the forever outsider.
oh and bart bass never comes back
