Reapers Lightsaber clashed with Midnights. It was clear she was both Force Sensitive and trained within Jedi Arts, or something similar. He eyed both colors of her sabers. One was orange, and the other was red. That was not normally a good indication.
Reaper unleashed a combo of swipes and spinning attacks against Midnight. He performed a mid-air cartwheel so as to swipe his saber down at Midnight - expectadly was repelled. She was well trained. As he landed a few meters away from her, he unleashed a current of force lightning. "What would she do in those situations?" he thought to himself, as if conducting a survey on her. He wanted to be absolutely positive in his hunch.
