Cyrus was right.
He told her once, that one day, she was going to find out that true love is really simple.
You just love the person, no matter what. You may stay or you may leave, but true love never dies.
She finds it is true , while booking a ticket for Prague. She prays he lives, because she cannot imagine him dying. She doesn't dare. Paris was a nice distraction from reality where she could pretend she was fine and moving on.
Reality is she loves him deeply.
Reality is they are Blair & Chuck.
Chuck & Blair.
