I think Claire has temporairly lost her sense of reasoning and she just freaked out because her son got sick. It wouldn't have mattered what anyone said to her, she was going to believe what she wanted. But we did learn that there is another facility on the island and the others are completely involved with the Darhma Initiative. Whatever that actually is but I'm leaning towards several different experiments going on.

You notice the keychain Ethan opened that medicine cabinet with had a Dharma logo?
