Neesa was surprised to see Christoph dive into the water after her, especially since he had to run across a battlefield to do it. Her first reaction was to be relieved, as he was doing his best to heal her, but once the rational part of her brain took over, she realized that this wasn't where he should be. His power was weakening, and the situation was made worse by the fact that he was using a spell of equilibrium to give himself more magicka. She opened her mouth in an attempt to speak, but her lungs were filled with blood instead of air, and nothing came out but silence. His healing was helping her, but if she, or any of them at all, were going to survive this, those bandits needed to die.
In the time Christoph had been healing her, Neesa managed to regenerate enough magicka to cast a rather useful spell. She looked over to the body of the Redguard and powered it with necromantic energy, drawing in the bandit's soul for one last fight on Nirn. The corpse sparked back to life, surrounded by dark tendrils of magic. It grabbed its blade from the bottom of the river, stood up, and walked out of the water, all at Neesa's command. She then looked at Christoph with an almost angered stare and pointed up toward the surface. He needed to get back in the fight, and though she couldn't speak to him, her gaze said it all.
