Zoe's power: Anyone else notice she might have some control over fire? This being based off the flaring of the candles and the fire in the fireplace when she's scared by the girls during her, "initiation" in the kitchen.
There's also some allusion to her having another power in the summary for the episode "Burn, Witch, Burn" - “Besieged by Marie Laveau's army, Zoe unleashes a new power. Fiona and Myrtle clash over control of the Coven. Madame LaLaurie is confronted by old ghosts.”
