There's not much to comment on from this episode, other then it is beyond dark, one of the darkest, most intense and claustrophobic things I've sat through in a long time. Very different from previous episodes, there was no lighter side, no human element, this was all about control, brutality and sadism. The episode served solely to give you an insight into the character of Dylan, his motivations, his bizarre relationships, with his victim, his monstrous mother and troubled daughter.
Very unusual, and at times a tough watch, with some incredibly upsetting scenes, I watched it on the edge of my seat. I kept wondering if the programme's title referred to the poor character of Megan. Is she hidden?
Interesting to see what's next, I found myself asking loads of questions, is Iona actually Dylan's Mum, is Nia really his daughter? So intriguing.
Rhodri Meilir excelled once again, as did Gillian Elisa (She was fabulous!) and Gwyneth Keyworth.
