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 प्रशंसकों rumoring how Jelsa "has" to happen in फ्रोज़न 2. They even started a FUCKING PETITION to put Jack Frost from Rise of the Guardians in फ्रोज़न 2.
I am fine with crossover shipping with डिज़्नी 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 आप ship Jelsa.
But just because a ship becomes popular, does not mean it will happen.
