I avoid spoilers as much as possible, as I like having the element of surprise when scenes play out. Unfortunately, I did see a spoiler about an acid attack, so was aware it was coming. I assumed though, that it would be Daisy who would be the victim. Which Justin intended she would be, of course, but it was shocking when Ryan got in the way and bore the main brunt of it.
What shocked me, because I'd never really considered it, was the fizzing sound effect, which I think really punched home the message.
I thought Daisy's "rant" to the police officer, listing everything she had done to try and get Justin stopped from stalking and harassing her, was very well done. The police officer was clearly uncomfortable at hearing it, and more than likely agreed with Daisy, that the police's hands were tied, and there was nothing they could do.
It would be wonderful if this storyline led to a change in the law, so that police can in future take action against stalkers.
It was a harrowing episode to watch, but so well done.
