"In Episode 1, I noticed that the statue of Betty in the garden is of her holding a pitcher with water coming out of it and it reminded me of imagery regarding Aquarius - an astrological sign often depicted as a water carrier.
The constellation is a reference to the Greek story of Ganymede, who was a young man taken from the Earth by Zeus for his beauty. He then served as the royal cupbearer of the gods for eternity and was even granted immortality.
I think the reason they used this imagery for Betty is because her story parallels Ganymede: she was taken by an all-powerful god and granted immortality in exchange for never being able to return to earth."
