Wait...

Adam and Lilith were created as a pair. A romantic pair. Except Lilith did not want to obey him.

Sera and Lucifer were created as a pair. A platonic/familial one. Except Lucifer did not want to obey the old ways Sera preached.

As Lilith ran away, a replacement was created. A new bride, Eve. Someone who will look just like her but more obedient. (this would also work with Eve replaced Lilith theory)

As Lucifer was cast out, a replacement was created. A new bringer of joy, Emily. Someone who will be like Lucifer, but with tight connection to Sera. Hence the similar looks of the two.

(If you think about it, Emily looks like Charlie, while Charlie looks like Lucifer.)

In the end Eve fell as well. And Emily is walking near the edge.

From her point of view, Blitz is to blame for her father abandoning her, and she feels that Stolas traded her for him.

But from Blitz's point of view, he includes her as his family ;(
