People say that they are fake but they look like quite much official. Everyone is judging the film by these posters that maybe are fake and they think Anna looks like Rapunzel, which is true. I don't know what to think about it
I never really liked this ship, which is why I've happily ignored it for months, and successfully have done so until recently. I've seen several fans rumoring how Jelsa "has" to happen in Frozen 2. They even started a FUCKING PETITION to put Jack Frost from Rise of the Guardians in Frozen 2.
I am fine with crossover shipping with Disney and Dreamworks, I even ship Elsa with Hiccup in How to Train Your Dragon. It's true I have many issues with this ship, but I don't care if you ship Jelsa.
But just because a ship becomes popular, does not mean it will happen.
