Constance Flynn-Fletcher

Constance is a 18th-century Candace lookalike. She is the disapproving governess of two small scientists, Phineastein and Ferbgor. She appears in "The monster of Phineas and Ferbenstein." She bears a strong resemblance to Candace Flynn in word and deed, writing in typical teen slang about her crush Jeremiah and ratting on the boys/scientists to an angry mob. ("I'm telling mob!) There is evidence to suggest she is the object of Jeremiah's affections- until she turns into a monster in a quite accidental turn of events.
