Karl arrives in Edinburgh, hoping to play happy families with his wife and daughter, she has to tell him the truth, and has a decision to make about which path she chooses.
Firstly, it's definitely an entertaining final episode, we go into this with one burning question, is she going to get away with it or not? The result, maybe that was quite hard to accept, but you can judge that for yourself.
There's a definite twist in store, it's a very unexpected moment.
Best scene has to be the collision of the two worlds, and what does Cath do, she just stands there as if nothing was her fault. One very definite conclusion you reach, is that Cath/Ali is an absolute monster, she's a horrible person. The one that suffers, is poor Molly.
Whittaker did a fine job throughout this series, hopefully post Doctor Who she'll return to lead roles such as this.
Entertaining, 7/10.
