Brockhill was a bouncer, fighter and traveller. She mentioned her down culture and what they do. I'm not saying what she did is what all travellers do but her culture is clearly very important to her and they whole toughing up Children.
Each time she hurt poor star, star was OK in the sense she didn't die or need attention.
So one can imagine it just escalating and her sort of becoming immersed in that world.
When I was 16 a very dodgy bloke fancied me and I sort of fancied him. Our date was hanging out in town looking at cars to steal. He was literally trying to open them as we walked along.
For a few hours I felt cool, walking on the wild side.
I think I saw him a couple more times before I came to my senses.
Strange as it may sound I think Brockhill was so so confident and assured that Smith did fall in with it.
I actually have noticed quite a lot in life just how powerful these incredible self assured people are esp when they talk in a certain way.
There is one at work, definitely not nasty or a killer liked Brockhill but definitely not that bright and yet very bright colleagues (some) really think she's something... I've got a relative like this also.
