Callie's attempt to reverse Miranda's cold-shoulder treatment of her backfires in a big way in a new sneak peek of this Sunday's episode of The Glades.

Callie decides to confront Miranda after she overhears the attending physician gossiping that Callie must have had an intimate relationship with Dr. Avery in order to have gotten her job. Watch to see Callie confront the aloof doc – and to see Miranda's revenge (and its impact on Callie's relationship with Jim) when the conversation doesn't have the desired effect.
