Things that the Ghost of Gabriella's Mother is afraid of:
1) The constant changing of Gabby's hair color is doing serious damage to her follicles, and she hopes she is using the right conditioner.
2) If Diane doesn't keep stalling that Gabby will be incredibly disappointed in how lame the ghostly warning is.
3) That her daughter could be gullible to believe a psychic who wears a turtleneck.
4) Diane's deformed hand.
