"Hey, listen to me," Claire said, kneeling in front of the chair. "I know the objections, I know the huge list of all the things that you and your dad and other people could begin to think of that could go wrong later, but everyone who's come out of those pits hasn't been stuck like this. They've all gotten past it. Even if these pits didn't make Sam's blood 'normal' again, he's not going to be stuck like he is right now."
It was the only certainty. No one could say this would change Sam's blood for certain, not until Sam's powers were proved to be gone and not just repressed, no one could say that this wouldn't ruin someone's live later on, but people could say the insanity would pass.
"I know the waiting sucks, hugely sucks, but he'll still be Sam, with all that means, when this is over," she reassured softly. "No matter if this works or not."
