I would have to imagine that the sucked souls could escape. The show seems to be pretty centered on hope– and so far all the characters who’ve sacrificed themselves for love have also been brought back by love. I don’t think Phillip’s story is over yet. I think Aurora will find a way to get him back. I feel like it might be more difficult than smashing it though, because or else why wouldn’t someone have already done that? I wonder if it would require some sort of substitution or even another type of sacrifice?
If Mulan doesn’t find her own prince, I bet she’ll make a sacrifice that allows Phillip and Aurora to reunite. Either that or she’ll just be a lone ranger and kick some butt out in the wilds somewhere. xD
