Michelangelo was a rather strange man? Did she mean the Michelangelo? Because if she did, what did that mean? Did it mean that she knew the Michelangelo, or was she mad? Both were possible, all things considered. If the former, given the woman's choice of clothes, Betty would have to conclude that Jeannie came from a different time altogether. If not that, perhaps she was immortal.
But if she was immortal, why was Betty receiving post-its with Jeannie's name on it. Immortals didn't die, hence immortal, and so there was no need for a reaper.
This was all very bizarre.
Maybe it was best to clarify. "Are you saying that you knew Michelangelo?" Because if she was, that was incredible, or an incredible lie. Which meant Betty might need to rethink what she was currently doing.
