I remember back in 3a when we find out Lydia is a Banshee. Jennifer says "You're just like me, Lydia. Look like an innocent flower but me the serpent underneath it." And I remember reading something and someone found a connection between Banshee's, Jennifer and Mermaids (I can't remember what the connection was for the life of me.) Now Lydia talks about The Little Mermaid in s4. I just find that interesting.
