Hello, just dropping in to say 'FFS!' about the stabbing, for reasons everyone's given.
DP warned me not to read anything before listening to Sunday's episode. I said 'why, has she stabbed him?' as I may have done previously too - because it's a silly revenge fantasy. Not because I actually thought it was likely.
Placing a knife in the hands of someone who wants to escape you, then mocking them and winding them up is such a ridiculous thing to do that I cannot believe the episode - in the same way I couldn't believe Nigel's demise because the 'shake to the core' nonsense told us it was externally engineered, not real properly part of the plot. Like then, it is only when other characters react to the news that I'll properly believe it.
Having said that and thinking Helen suffered a sudden loss of control - or possibly something that was or could be presented as self defence - another thought.
Knowing Helen as we do, I cannot help feeling very uneasy that she feels sure she has slain a monster, so that's just fine. It strikes me that in opening her eyes to a Rob and regaining control, she has on the one hand continued to be self-doubtingly suggestible - by swallowing wholeheartedly Jess's assessment of Rob as a monster. While, on the other, re-asserting her controlling tendencies by ruthlessly banishing Rob from her and her children's lives. I felt no doubt that her 'but he can't be alive' was in the same vein as 'but I can't be pregnant', because these occurrences were not what she'd intended. He said then started to show her that he would always be a malign presence in her children's lives. She said then showed him otherwise.
That makes her both mad and bad. Not to she wasn't also very sad, snapped and lost it which, in a somewhat parallel worlds way, I think was the case.
