No, they didn't. They climbed on the boat from the water side,not the dock side. Yes, I too wonder what's up with all the miraculous cures. It's clear that the original organization that built the facilities is playing some sort of experiment here. Maybe you're right, that the 2 islands are part of an enormous biosphere. Wasn't that all the rage in the 70s and 80s? That doesn't explain the healing properties though. I'm wondering if the whole show isn't supposed to be an 'what if' about purgatory.
