Magnus, you're mentioning what is learned in a subsequent episode. At this point, it remains a possibility that the Room has gotten bored with death and insanity, and has decided to turn to shape-shifting.
I was surprised to see Catherine declare her love for Morgan in the drawing room, after all the ugliness that we've seen in him. But she's seen less of it than we have, and now that she's married to him, she might as well try to make the best of a bad bargain.
As Julia and Morgan stood outside the Room, I thought to myself that this was not the first time that Julia has waited outside while a family member went into the room. She remembers when her brother Justin went in ten years ago, and she remembers living through that night. By the way, every time the voiceover says that somebody goes into the Room once every generation, I think: "Ten years is not a generation." All I can figure is that there had been a longer time than usual between Justin's Room night and the night that the previous person went in.
Suddenly, seeing the names Justin and Morgan together in what I just wrote, Justin Morgan Had a Horse popped into my head. Justin Morgan was a real person. Were the writers thinking of him when they named those two characters?
The scene between Bramwell and Catherine was utterly convincing.
