Allison Might Not Be All That Innocent
During the lighting ritual of the black flame candle, Max is a gentleman and asks Allison if she would like to do the honors. If you recall young Dani’s reminder in every other scene, a virgin has to light the candle to bring the sisters back from the dead. Disney’s not-so-subtle way of having Max ask if his love interest is still a virgin. She smiles, blushes, and declines.
Allison’s shy response to not lighting the candle is meant to be a sly hint that she is no longer a virgin. Way to be smooth, Disney.
