Also the Georgia thing was so confusing. So she hit a child with her car, she left the scene, the child died, and it turned out she was speeding. But the police decided not to prosecute because it was "an accident".
So in Scotland are you only legally culpable if you literally drive your car at someone with the intention of killing them?!
And Paula forgave Georgia but hated Kay so much she killed her and hated Ellen so much she wanted to ruin her life.
The radio times article is nearly as frustrating as the episode, everything that doesn't make sense is explained away as Paula being "mentally unstable", Ellen just had a lucky guess that Lia was in the library, and the writer hopes Paula "gets the help she needs". Ummmm. Well yes, and also goes to prison for a long time, for baby kidnapping and murder?!
Ok, I was possibly a bit overinvested in this series but it had such promise! Last night was really disappointing.
