In which Erik puts his foot in it. Deep.
For those of you who haven't seen Rise of the Guardians, Jack Frost spent about 300 years invisible and intangible to human beings. (And is not, upon recollection, the only incarnation to be incapable of interacting with them, so double the effect of that...)
Erik belongs to Leroux and Webber.
Jack Frost belongs to Joyce, Ramsey, Steinberg, Berstein, Abaire, and Pine.
