David had been observing the available energy resources in the energy plant they were at, and electricity was a abundance here, but it was necessary to be sent elsewhere like the city where it was needed, so he had crossed it as off limits unless in an emergency. He had been perhaps the very last one to be transported over and thus was also the last to react out of the whole group as well with his observation on his environment it was. However, everything seemed to happen so quick as he was snapped out of his examination of where his battlefield when he heard a snap and quickly glanced as he saw Samantha, or Witch fall down after being killed by the Immortal. 

It was a shock, yes he had seen people die before but in front of him was a girl that had so much potential in her life, yet it was smothered out. Never showing her true potential in the world and soon to be forgotten as well, but David pushed away these thoughts as he blinked furiously as he realized his eyes were becoming teary. He forced himself to gather himself and access the situation, and look what was happening with the battlefield.

He watched as the chimera charged at the insanely strong meta-human and then came the opening he needed, as Gloria aka The Specter, slammed the man into the wall and- phased him, partially through the wall leaving the man temporarily stuck with his hands immobilized. It was a good opportunity but it would be sore experience the next day, he had to give it everything he had and too went to finally join the fight. Passing Specter and standing right behind the Immortal, The Elementalist concentrated on the concrete flooring along with the walls and focused on the the water, cement and a another foreign element he wasn't too sure what it was but he could feel it as well. Manipulating all three elements, the concrete began to climb up the Meta-Human's legs and arms before digging into the clothing and then tried piercing the meta's flesh trying to imbue itself into the man's body while it climbed it. At this rate, it was significant but within no less than minute and perhaps sooner, if the Immortal didn't escape he would be entombed within a concrete coffin. Maintaining the growth and movement of the elements was a difficult challenge for David in this situation and pace however, he managed as he watched the concrete he was controlling doing its work on the man. He had started with the mans legs as his main priority before his arms but there wasn't much of a difference in the progress of either of the two.

From the corner of his eyes, he could see the Specter running off but he couldn't follow her as soon she got out of his line of sight, he was back on paying his full attention to the Immortal that he was trying to keep immobilized.
