Timeless comes from the creator of Supernatural, so it's really no surprise that we will be getting a visit from Bobby, or should I say from the actor that plays him in the CW hit series. Jim Beaver will be appearing in the final three episodes of Timeless as NSA Agent Neville. He will come to Mason Industries to lock horns with Sakina Jaffrey’s Agent Christopher, TVLine has learned. (Kripke first announced the casting via Twitter.)
