It strikes me that Dirk addresses Quentin in rather a contemptuous manner for a subservient to his superior ("hey, what are you doing down here?").
Moreover, why is Barnabas so eager to jump into all this mess involving the will when he has no idea of how he might be affecting history with his actions? You'd think he'd be more restrained and willing to play the part of the dispassionate observer, at least until he'd gotten a better lay of the land and figured out what he should do to bring about the desired result for what was happening "back" in 1969.
