YMMV / Merlin S 01 E 01 The Dragons Call

• Fridge Logic: The witch in this episode has the power to teleport in a self-made hurricane, kill people by stabbing a straw effigy, disguise herself as anyone she wishes, and stop time itself by singing. Is there a reason she didn't instigate these powers before her son had his head cut off?
  • Maybe she wasn't there when it happened? Or maybe she just wanted to live in peace and the execution of her son drove her so mad with grief that she unleashed her powers with no restraint.
