Unfathomable

Unfathomable: Incapable of being fully explored or comprehended. Impossible to measure the extent of.

Enid has to return to a home that doesn't see her for who she is and try her best to survive until things go haywire and then it's Addams-to-the-rescue and together they begin to understand what (or more specifically who) their true Home could be.

Or: what happens after the events of the finale, starting right at the Hug™ moment and following Enid and Wednesday on a journey of self-discovery, understanding feelings, and finding what truly matters.

or OR as I imagine Wednesday would say: 'What is this... Unfathomable feeling that is creeping in and growing freely inside of me like a flesh-eating fungus?'
