Chatting to Julie about this week's episode, and the following occurred to me:
Either Eeeevil Belle will fall for Gold and then, when they get True Love's Kiss she'll realise what a terrible person he is, and want nothing to do with him, or he'll realise that _he_ doesn't love her when she's not Good, and so while she falls for his bad-boy side, he no longer has the feelings to free her from the curse. Either way around, it's not going to be good...
