I also didn't like the way last week's promo deliberately deceived us. They showed the Bridget/Siobhan slap scene & indicated the truth came out. Come to find out it was just a flashback.
Also, I missed a bit toward the end. Who's child was that & how did he die, & what did the father have to do with it & what did the father have to do with the non-mother twin?
You walk out of the room for just a moment & everything goes crazy.
