Inappropriatefemale " I really thought that she would’ve eventually came round and spoken to Beckys mum but she was too snobbish for that."
I'm not sure it was snobishness. I think there were at least two issues here.
One that people united by a terrible shared trauma may not naturally gravitate towards each other. I don't have any idea for sure but couples who lose a child, do they usually stay together? Or sometimes does the shared tradegy make it harder to be around each other?
Secondly, I think Sian's mum was worried her daughter might be considered a prostitute or druggy because she was killed by the same man as Becky.
When she said about it back in an earlier episode, I felt very sad. But maybe she could not bear the thought of people thinking badly of her girl.
