I loved this. Made me have a good think, and unlike most "dead/missing children" stories, it actually had an emotional impact on me. Kiri was so sweet.
Also, I love Lia Williams so much (she plays the foster mother). Agree that all of the foster family are bloody sinister though.
Kind of surprised by the beating Miriam has got from the reactions in general. Yes, she is EXTREMELY flawed (drink-driving, calling Kiri stupid was a really WTF moment for me), but to me, it showed both sides: Miriam overworked, constantly overwhelmed, and dealing with some truly harrowing stuff. And genuinely caring (agree with PPs that this is co-dependent or somewhat unhealthy, as with the addict, but she clearly does care.)
I too think that the son is a red herring. I think it'll turn out that while the GPs let their son (stepson in the DGM's case) go off with Kiri, she was actually kidnapped from there, rather than from the house.
By whom? I think both the bio-dad and foster brother are too obvious. It turning out to be either the foster brother or the foster dad gives me major Broadchurch vibes though. That basically only leaves the foster mother, but we saw her sitting in the car at Kiri's GPs house. So she's under direct suspicion now. Okay, I'm going for the foster dad (as he's the only one direct suspicion hasn't been thrown on yet) but I hope I'm wrong.
In addition to the big topics, I liked the little details or more subtle lines. Like when the GF asked the female police officer (who was also great in The End of the Fucking World) "where are you from?" and she said "here" very pointedly.
Possible clues/red herrings:
- The nosebleed. Yes, Kiri left the blood in SL's car, but what else? Can nosebleeds indicate some kind of violence/abuse? Or even natural causes?
- The focus on Kiri's neck. I'm gonna guess she was strangled with the scarf but there seems to be a lot of focus on it, like the foster mum and Kiri talking about it.
- Kiri says Alice asked her to call her mum. Did she mean that day?
- A bit was made of Kiri running away before. Could this suggest she's seen her dad before (or someone else...? Or maybe a reaction to abuse or something else?
- Also, was it ever mentioned what happened to Kiri's mum?
