I don't believe Ted did anything wrong. People do all kinds of weird stuff while they're asleep. Have you ever woke up & wondered how the sheets got on the floor & you were all turned around & in the fetal position? Trust me on this one folks. As a married man myself, all kinds of weird things happen while you're asleep & you don't even know it. So this is hardly something you can blame Ted for. At least he was man enough to apologize for his involuntary actions.
And if Ghandia was so traumatized by the whole experience, then why did she kiss Ted after winning the Reward Challenge later in the show?
