What i imagine as a nice ending for the Heidi/Athena path:
Since polygamy is illegal in the US, Jackson decides to marry one of them (gotta choose) to "keep up appearances" and the scene at the wedding goes:
at the altar he's facing his chosen bride, with the one not chosen right behind her as bridesmaid and as the priest goes "do you Jackson take Athena/Heidi as your wife, etc." He looks at his bride, then slightly glances at the bridesmaid, making her smile then looks back at the priest and says "i do". cut to some time later the 3 of them happily together as one big family and both girls pregnant.
but oh well, a man can dream....
i know we'll be more than happy with what Storm and Slockie are preparing for us!
