Wow! What an episode!
So I think Lena was killed by Gettrick because she found out about Alice and Sophie and threatened to tell. He then needed to dispose of the body so she ended up in the shed. Doesn't explain how the DNA matched Sam's; either the DNA result was lied about, or Lena is Sam's, or the body in the shed was actually Alice's child? But if that's the case, where is Lena?
Why is no-one concerned about Jorn? I know Gettrick texted his friend pretending to be Jorn and said he'd be away for a few days but surely someone would be asking questions?!
I got the impression from Sophie at the cabin that she actually doesn't like Gettrick and is biding her time until she can escape. I think she's playing along to keep her daughter safe.
The PP who said that Gettrick has left his wallet at home which will have Swiss francs in it, so Gemma and co will know where to go, you're a genius!
Need to know what is in the basement. Also need to know how on earth Gettrick managed to get them out of the house and to a theme park without anyone noticing.
The thing with the Brig and the turtle that he told to Sophie; I think he and Henry Reed are the turtle, Gettrick and Nadia are the birds? If either of them squeak, Brig is in a whole heap of shit for going off base against orders, shooting a man, burning a house down and killing a little girl. His career would be shot. I think he knows what's going on with Gettrick but can't speak out because Gettrick is maybe blackmailing him? So he is complicit in framing the butcher as it keeps Nadia quiet too?
I really need to re-watch the previous episodes to see if anything makes sense now we have more info!
