Yep I think Jack is still harping after the Amanda of his youth and only got together with her because of the memory of how close they were. I'm not sure how he would respond if Emily-Amanda told him the truth. He may be too betrayed? I think he'll find out soon. I also think there's a strong possibility of Fauxmanda leaving. Perhaps they kill her off, thus solving the issue of what to do with the baby?
Declan has turned to burglary as the boy he was with paid him to hold on to something (possibly weed?) and probably paid him to help him burgle that house. Declan needs money to make it on his own and give Jack and Fauxmanda space with the baby coming. I think it was a set up and the owner of the house will turn out to be dodge and try to blackmail Jack/Declan.
Ashley always said she would do anything (or anyone) to make it in the top social circles, hence her clinging to Daniel like a desperate limpet.
Daniel wants to protect his family and the business but clearly doesn't know who he can trust.
Isn't Nolan gay? Not sure how the new accounts girl comes into it...
Perhaps Emily-Amanda's mother isn't actually her mother, hence why the mother hasn't tried to find her?
My afternoon off has been productive pondering all of this
