Aredo3604 I agree with most of what you say. I don't want to sound hyperbolic, but I agree that it makes her enough of an unsympathetic character that I'm not really interested in watching the second season anymore. It also pretty much makes it impossible for the show to end well. Assuming she does make it home she has to admit to her husband and son that she had an affair while she was away. Lets assume her husband turns out to be evil she didn't know that at the time and she also still betrayed her son.
Aredo3604, I'm not sure about you but the main reason I find this disappointing was becuase it takes a charter who has one of the stronger female heroines on TV and makes her pretty unheroic. Betraying your husband and young son pretty much makes you a louse.
