As Jamie ducked down, Mia did a graceful somersault over his head. It was something that she'd been able to do before becoming Force sensitive, and the Force only enabled her to take her gymnastic skills further and make them more graceful and complicated.
Even as she flipped over him, her lightsaber was already out in mid-air, singing, humming, slashing, and cutting off the heads of the zombies in a well executed move that could've only been planned ahead of time with the Force. Her lightsaber came too close to crossing the space right where Jamie had been standing moments before, which is why she'd had him duck. She landed right in the thick of a group of zombies that had been headed for them, taking them out in record time with well-practiced lightsaber moves that looked more like a dizzying dance than anything you might use for combat.
