S1, E4: Cassie looks up an old friend of her mothers named Heather Barnes (recurring guest star CAMILLE SULLIVAN Shattered) and discovers she has been in a catatonic state since the night of the fire 16 years ago. Feeling guilty that her mother and her Circle may have had something to do with Heathers current state, Cassie tells Diana that she wants to use magic to help Heather. Diana refuses to help, but Faye is more than happy to conjure up a spell for a price.
