Calling this a simple task for Ralph would be a blatant lie. His mind was in Turmoil as he began to think of how he would be harming Grace by doing the very thing she needed to help her.
There was one thing that he was certain of. Clark was not the kind of person that would mislead or intentionally harm anyone.
Therefore, Clark had been honest with the method to help heal Grace. If he followed the I frictions and had Maria prepared, they could save her.
There was also more that he was noticing. He had felt pain. He had been the cliche kid that grew up on the streets. He wasn't the same as many people that were within Nova City. He didn't piss someone off and get forced to his low class position. He was born and raised there.
Creation is hard, cheer me up!
