Quote equalityboy81: Who is Melanie Layton's mother? Nicole maybe? Why isn't Melanie's last name Robbins? Where does the name Layton come from and why was her mother never revealed?
All good questions and I think they leave this sort of stuff open for "future use" instead of introducing a character with a fullfledge history and backstory. As we are witnessing with Rafe they are writing it as they go along, back in the Safehouse they didnt know were they were going with this character and didnt mention any siblings, now we have 1 sister on the scene and another fixing to appear.
Mia is in almost the same boat as Mel except we know even less, not even about her father. But there is rumour of a connection to Carly, might Carly actually be Mia's bio mom???
