So I got ahold of Nolan and had him come over to look at the note. Obviously, my first assumption is that he could have sent it considering his pension for the paranormal and all and the fact that he wants me to be a Luiseach and be some sort of paranormal warrior against evil ghosts and spirits, or maybe just evil in general. But when I showed it to him he didn't seem to have sent it. So I guess it's possible that someone else sent it, or the person who originally sent me the photo of the ghosts sent it to me. What do you think?
