I'm rereading Lady Midnight and I saw this:

What do you mean, Cassie??? She just loves to confuse people by putting small things like that in her books. Is there some weird connection that we don't already know about with Lady Midnight and The Last Hours??? Something that hasn't been explained that we don't even know exists??? Seriously!!!! This is driving me insane!!!
Also, sorry about this mini-rant. I just noticed this and then my brain just went haywire. Goodbye.
