The experiment.
Logan says looking at her asleep, but her face was still set in pain and tears, he believes it's not a physical reason, I was on his side too, but we had to check.
"Finish the test and let her sleep the day off, keep an eye on her vitals, tomorrow we'll try again. Don't forget the soundtrack," I order them again, leaving them to their job, she's out of it, the tests won't take long to do.
Soundtrack number two includes my strong voice telling her to let go, repeating the words "you are safe with us", over and over again, we're trying to gain her trust, this is one way to gain it, she needs to trust us before they could allow her to move again.
