The wording of the beginning voiceover suggested to me that the parallel time room was created by Barnabas's subconscious to distract him from the troubles that are besetting him in his real life. It's not true (I don't think I need to make that a spoiler) but I wonder if Julia had considered that possibility. The book that Hoffman threw out of the room, however, will dispose of the delusion hypothesis, once somebody besides Barnabas sees it and handles it.
I was disappointed by how gently Hoffman threw the book out of the parallel time room. I suppose there was fear that it would be damaged so that Barnabas wouldn't be able to read the title, but the gentleness of the throw was still uncharacteristic of Hoffman. If I had been there, I would have had two books available, so that the book that was thrown could be replaced with an intact book, if necessary, when the camera wasn't looking.
After everything else that Willie has seen and done at Collinwood, I was surprised that he was carrying on so about staking Megan. But I guess he thought his life had changed when he met Roxanne, and now here he is, doing the same old same old.
As Roger guarded Megan, I wondered what the cannery staff were thinking when he didn't show up for work. And then Megan was staked, and Roger remembered nothing. Other vampire victims have remembered things after their vampires were staked, but Roger remembers nothing. Elizabeth made a comment elsewhere in the episode about how the Collins family is good at denial, but Roger doesn't have to go to the trouble of denial because he doesn't remember a thing.
