What a stupid episode this one was.
For a start, Sienna's obvious lie about the "father" was totally unbelievable. The writers who wrote that, completely re-wrote the story of Sienna, the 13/14 year old who had a baby that died shortly after birth!
Not only did they re-write Sienna's past with that lie, they gave Nico amnesia too. Nico knows that Patrick lied to Sienna that her baby died at birth.
Then to go on and say "he wanted nothing to do with me or you". Errr, no you thought your baby was dead, you had no idea your child was alive. Not only that, Nico was put up for adoption!
Sienna's character is good at lying, the writers were just being very lazy sloppy with that one.
Also, if the "father" in the lie went into the army and to war, what was the age gap between him and Sienna? Don't you have to be 18 before you go to war? Sienna gave birth at 13/14 (cant remember which).
Don't even get me started on the rape storyline, how fast Ste has recovered from the loss of his father and being in a coma and cheating on JP! The less said about the boring gangster stuff, the better.
