Something I feel is underutilized is /co/ntainment. I think this because the scope it always too big, like being out in the field so the plot never actually forms.

Take Captain Rookie for example. She can sense/see ghosts even when they don't want to be seen. Sure, sounds grim and dour, but a lot of people die. What if she encountered the ghost of a mime or a clown or some other type of entertainer who just wanted an audience again?
