WHAT DO U THINK?

I have no idea about the official storyline, but I'm guessing that, he give her the crown because she's feeling down letting her dream to became a princess go? And he take her to the MET step to make her remember that she still blair waldorf who are the queen B of UES,and leaving because they attack por little minions,lol,it's just a guess though, maybe someone should write a fanfiction about this XD
