Glad I found this thread! I watched the first episode last night.
My thoughts so far:
Tom definitely gaslights Kate - the whispered antagonising at the beach and the putting the wine in her hands - remember Girl On The Train, the alcoholic whose husband convinced her she had a problem to keep her in line? You just knew as soon as he said quietly “go then take the children” she would react and look like the bad person. Why would he ply her with drink then send her off with his kids in the car? Very odd.
The MIL is definitely off - the way she said she didn’t want him to wake up in the hospital was quite sinister.
I can usually spot an affair in a show a mile off - I said to DH when Tom hugged Jess goodbye after the barn dance “there’s something there.” I think Jess actually participates in provoking Kate, be it from jealousy that she is married to Tom/has 3 healthy children or some other reason, but the way she kept going on in the car about “how much Tom adores” Kate just set my teeth on edge, she could see Kate was stressed already trying to break up the girls’ arguing in the back of the car but kept poking about the mother in law etc. She also went almost in to a parental role at the beach saying to Tom “I’ll go with her” as if Kate was a stroppy child needing looking after.
Something else that stood out to me was when the police officer walked past the park, it was such a sick remark “did you see any bodies?” I think the teenager on the swing said. The copper showed signs of PTSD panicking in the car about not being able to save them etc yet he was so casual and took it in his stride they were making jokes about the bodies of dead little girls. Unless I misheard that?? I was angry just watching it! Not to mention they were supposedly very close friends.
I don’t think the police officer (sorry I forgot his name) trusts Jess, DH couldn’t understand why he hadn’t mentioned the padlock to her as she is his wife, I said maybe he’s being professional, but thinking on it would you be able to keep that to yourself from your wife when it’s about your best friends?
I don’t trust Kate’s GP one bit. He seemed to like suggesting she was unstable, so unprofessional and personal. The headteacher seems to be in love with her I agree with other posters on that!
I cannot wait for the next episode!
