We’ve seen that Pan has a Shadow (301) so do we believe that his Shadow can detach itself from his body at will? Or is it really NOT Pan’s shadow.
In the Peter Pan story, the Shadow is an extension of Pan but I think we’ve seen that the shadow can act/behave independently of its host. (the shadow posed as Belle, to distract Rumple). Unless that was Rumple’s shadow and not Pan’s? Do we know?
The fact that we have Marilyn Manson as the voice of the shadow, makes me think the shadow is a separate/independent entity from the person. The shadow is aware.
