That quote comes from (don't be surprised) Pocahontas U__U
This is my fav Disney because the colors are vibrant and the songs just wonderful... =3
I translate from the french... That wonderful phrase isn't in the English version... ;__; (a question of rhymes XD)

Avant que le ciel explose,
je dois tenter quelque chose

The picture comes from animepaper.net (I guess)
Pocahontas (french version) - Des Sauvages : Here
