There will be an angelic counterpart to Chrissy.
This might take a while, but at some point, we might meet a character whose parent is either an angel, the archangel, or Jesus Christ himself. They could either be a rival or potential love interest to Chrissy. Laura's love interest will be Satan or Darlene
I'm not entirely sure that Laura's going to get a love interest at all, but if she does, I think it has a high chance of being Darlene. They've already got some Les Yay subtext by the third episode. If not, my next best bet would be Satan, but less so, since he was abusive.
