So Alias, Adam's simple statements concerning relationships turns out not to be as simple as he first thought?
He is choosing to ignore those very disturbing, and I would say, dangerous, thoughts she had - just like her doctors, BTW; and of course ignore that Colin said that Sheila´s condition invariably deteriorated when she visited WHF. Instead Adam repeatedly calls it "a free holiday".
None of them wanted to be there, not Sheila, not the twins who BEGGED Colin not to go when he had driven them there!
