Yumi wasn't moving an inch with Viral staring her down like that, she couldn't. The animal instincts in her screamed to stand her ground and don't run away, that was a show of weakness. Yet her common sensibilities told her not to fight her friend, that he needed to be kept at arm's length so he didn't do anything he'd regret. When he lunged for her she prepared to dart away, watching instead as a few spikes found themselves into his side. Gasping she looked at the creature in disgust, turning to try and attack it instead. Before she could even lift her hand however it was pulled off the ground by Viral, being yanked as he dove beneath the ground, snapping the tentacles binding him. When it turned on her again Yumi was ready, having come back to her senses somewhat by now. Again Viral got in the first blow, grabbing the creature up and throwing it aside with his jaws, leaving her sitting there stunned in silence. From all of the goo emerged a humanoid figure, apparently the source of all of those attacks. So was that the real enemy then? Seeing it distracted by Viral temporarily she took the chance and dashed over, moving as quickly as she could with the aid of Ki and coming up behind it, trying to smash it down with an overhead kick. 

There was the second vial, now for the last two. Gods did he feel lightheaded, just what in the hell had that creature done to him? It didn't feel like a poison, there was fatigue and a lack of accessibility to his own Ki, so had it sapped his energy? No matter, his job here was to get the system running and purify the reservoir, he could do that much still. Placing in the final two vials he sealed up the pipes again, restarting the machine and watching as the solutions were pumped out and sent down into the filtration systems. Taking a glance back at the fighting to see if everyone was okay he turned to the machine again, watching as the last few drops of the solution drained through before turning valves to let everything empty into the water below the dam. It would be some time until they knew for certain it worked, but with the creature out of the water he was confident it would do the trick. Now for Yumi and Viral to bring it down, then everything would fall into place thereafter.
