Leo let out a groan of vexation at the wasted opportunities, but quickly collected himself and started charging a powerful blast aimed at the ground, in order to give himself time to get away from the prideful girl - seeing as she didn't do anything yet other than approaching her targets, her Lumen was obviously short-ranged. However, a weak glare, whose intensity was reduced slightly since it was reflected by his glasses, caught the corner of his eye. Light manipulation. The young inventor could feel his skin crawl in indignation once he realized that not only he missed, but he also got his two targets to gang up on him.
However, a loud sound brought him back to his senses. He quickly realized who was the only person that could have made that noise and, remembering his assailant's current form, used his own metallokinesis to lift Jev up. Right before throwing him at Aria, though, Leo gave him a light tap on the shoulder, releasing an electric pulse into the shapeshifter's highly conductive body that was just strong enough to immobilize him for a minute or two.
Unfortunately for him, that convoluted maneuver was exhausting. The electromancer made a hasty escape to the southernmost part of the arena, where the other metallokinetic was standing at the beginning of the fight, while both his foes were distracted by each other.
