Other mistake: Mr. Gellar never ages. We see a flashback of him when he kills Sarah's Dad when Sarah was a little girl. When Sarah is a detective, he still looks the same.
Sara Pezzini: What is this thing? What is the Witchblade?
Kenneth Irons: A mystery, wrapped in a riddle, and cloaked in a conundrum.
Sara Pezzini: That doesn't help very much.
Sara Pezzini: And that's the story of how I came to have this strange thing on my hand called the Witchblade. I still don't know exactly what the Witchblade is, or how to use it. Every day I gain a bit more control, but this control requires will and vigilance. I think of Danny a lot. He was right. Everything and everyone is more connected than we realise. So there is no pat ending, no neat finale, no single final image.
