Maggie doesn't know she's living in a supernatural soap opera. Most of us would even deny the evidence of our own eyes, before believing in ghosts, I think.
Yes, I'm pretty sure that I would.
Sarah's so interesting. Maggie asks her, "Why did you come to see me?" and Sarah says, "I don't know." I thought she was reaching a point at which she had some control of her existence - but apparently it's still shaky.
Julia is usually smarter about Barnabas than she was today. Is she indulging in wishful thinking? "I, Julia Hoffman, have a vampire wrapped around my little finger" - whereas it's going to become more the other way around.
I loved the ending. It's not the first time we've seen Barnabas looking out that window, and it won't be the last - but I always like it.
