I can believe the Todd/Theo story. People do get 'bewitched' by abusers, and find themselves unable to pull away. Todd has done well to get this far, but the problem is that if Theo promises to make things the way they were when they were happy together, Todd might relent. I really want Theo to be exposed for the bullying abuser he is.
It does look as though Leanne has seen through Megan. I hope so, as she's a monster. I'm really warming to Sam. He was such an odd child and I found him difficult to like, but he's morphed into a slightly awkward but pleasant teenager. It's horrible to see him bullied by Megan, and I wish he would confide in Leanne (and not Toyah!).
I know people have different 'tastes', but what a grown woman gets out of a sexual relationship with a young teen is beyond me. She is risking her career, her liberty and more for the 'thrill' of sex with a boy. How old is he? About 14?
