you know, one theory out there in the interwebs is that Anna and Elsa's parents died on their way to Flynn/Eugene and and rapunzel's wedding, then shipwrecked on an island before being eaten by a leopard. that may or may not sound familiar....

I heard that Anna and Rupunzel are cousins so wen the parents died, Rupunzel and Eugene came to arendelle and if u pause the movie somewhere in the track for the first time in forever, u will see Rupunzel and Eugene !!!
