The morning of the exodus from Boston, Aunt Kate is helping her husband, Uncle Scott, try to start an old stationwagon . Captain Weaver tells him they only have ten minutes before they have to move out. Their niece, Anne Glass, then approaches carrying a box of medical supplies, asking if she should load them in backpacks or his car. Scott says "The car", but Kate is afraid he won't get it started and leans out the window and tells her, "Backpacks!". Miraculously the engine sputters to life and they load the car just in time to move out with Captain Weaver and the 2nd Massachussetts unit. ("Live and Learn"). Aunt Kate argues vehemently with her husband when John Pope (Prisoner of War)is recruited as cook. She doesn't trust Pope, but grudgingly admits that his soup tastes "pretty good....considering." Aunt Kate organized the women to give a baby shower for Sarah who was pregnant in (Silent Kill).
It isn't revealed what happend to Aunt Kate. She's presumed deceased like her husband Scott.
