When Henry's face fades from the mirror – Emma is still clutching it in her hand – the glass goes black, and she knows why, the mirror twin must have been broken, is Henry okay?
Has Pan found out that they are trying to reach him?
Is her son currently being… punished… because they wanted to give him hope?

Emma lowers the mirror, she's smiling – Snow is smiling too – and she can't help but feel that twist of worry and fear that has become so familiar in the last days… she clenches her fist, and involuntarily squeezes lightly the heart she's holding.
