Mrs. Teasdale volunteered to "grief counsel" the Nine Airborne Princesses at the same time that Agrippina became their guardian near the end of the 24th storyline, "A Long, Long Trail A-Winding."

Since then, they've been through 2 whole books, the last of which lead to Mrs. Teasdale becoming a Knight of the Chiaroscuro--check here for details on that.
I'm sure things'll get even more confusing as this story progresses...
