Wait, I thought that the whole "Hippolyta being attacked by Hercules" thing was referenced in the Wonder Woman storyline based on a potential movie about Diana that she was over seeing?
Where they showed it as conscentual which ticked Diana off because it wasn't.
Also, Cassie DOES have a rejected suitor: back in her mini series Hercules made a pass at her (her being his half-sister is referenced*) because he wanted to make a new pantheon due to the Female Furies imprisoning the old ones.
*If I remember correctly he said that Zeus and Hera are brother and sister, so it should be ok or something.
