Lilith Pleasant/theories

While the reason is never given, it is quite obvious that Lilith Pleasant's parents overwhelmingly favored Angela. Why is unknown. Place your theories here.

Theories

 * I think Daniel and Mary-Sue only wanted one child. It does appear to be that Angela was born first, since she always grew up before Lilith and (According to Daniel and Mary-Sue's memories) was born first, so maybe the parents were content with Angela but wasn't happy when they found out they had another child, and therefore probably didn't treat her with as much affection. I don't think they abused her though, since the Pleasants are over-confident and stuck-up perfectionists, they probably wanted to maintain that appearance, so Lilith wasn't abused, but she wasn't loved either. That's just my opinion.
 * The theory above is good, more I think only that Lilith is the rebel type of child just like Dustin Broke.
 * i think that the pleasants were expecting only 1 child, and that was angela. i think that the doctor gave them the wrong info.i think that they had another name just in case and that name was lillth.thats the only way to me that it would make scence. from, bvbfan1
 * When Mary-Sue gave birth at the hospital, and after they closed her stomachand sent her home, she felt pain, went back to the hospital, and unhappily gave birth to an evil rebel child, named after the evil lady in the bible lillith
