Doing a Read-More, I’ve already 発言しました some of these but I’ll just repeat them so I can just concentrate on Dan/Blair :

Blair doesn’t have feelings for Dan
She only likes him as a friend, and tells him so.
Dan likes her a bit but knows she still loves Chuck.
Blair decides to be with Chuck but Chuck ruins it so she changes her mind and isn’t going to be with him until he’s ready.
The Prince comes and Blair goes into this “fairytale” mind set and basically isn’t living in reality.
She fakes being with Dan for like one scene so that she can secretly 日付 the Prince
Serena freaks out and tells the Prince that Dair has been dating even though they haven’ts (she’s jealous/angry that Blair kissed Dan)
Chuck VS. Prince is going to happen. Blair has to choose between them two, NOT DAN. He’s not a contender.
Dan gets with Charlie who is Serena’s cousin.
So, Dair doesn’t happen. Blair has to choose between her white prince/dark prince and Dan is going to be somewhat with Charlie. THE END.
