Evvie was breathing hard at the end of that exchange due to all of the fire she had to put out. She was relieved when the next attack turned out to be fire, which was nothing but a pleasant bath to her at these temperatures. She used this time to rest, nonchalantly bending over with her hands placed on her knees, her chest heaving in and out. She didn't want to stay inside the flamethrower for too long or else things around her might start burning and then she'd be taking huge puffs of smoke into her lungs, but for now she'd be fine. 

If she had time to properly catch her breath then afterwards she'd rush forward to make a stabbing attempt at her enemy's stomach with her fire sword. If the enemy tried to run away then she'd do her best not to let her get too far away, which would give her a chance to fire more of those strange explody things or the electricity.
