Like Ariel, Eric will first be introduced in the sixth episode of season three and will be part of a multi-episode arc. But that’s as much as we know at this point since the producers are keeping details under wraps as to how the mermaid’s story will unfold and where her prince fits into it.
While it’s easy to assume that Eric and Ariel will have a romantic relationship, fans of “Once Upon a Time” know the producers and writers enjoy putting their own spin on classic fairy tale characters.
So far, we know Regina (Lana Parrilla) has made it clear that she’s not a fan of mermaids. How will she fit into this story?
In addition to “Supernatural,” McKinney has had roles in “Perception”, “Grey’s Anatomy”, “Major Crimes” and he played Derek Bishop on “Friday Night Lights.”
TVLine was the first to report the casting.
