I just have to say that I got very teary-eyed when Marc Klaas began talking about BD saying that she is not in denial, etc. Marc knows exactly what BD is going through, and I believe he is there to support her, not to judge her. When I saw BD crying, (and I really believe she was crying), It was my opinion that she felt "safe" having Marc there, and was finally able to let go and cry a little.
I don't agree with all "mis-speaks" she has made about SA, the affidavit, etc. etc. and she is probably still in love with SA and trying to protect him. But Marc is there for her, and I am glad she has someone there right now. I do feel she is in denial of some sort, but I also believe that she needs to be in denial because she is not emotionally ready to face the truth.
When my great Aunt was diagnosed with cancer at age 91, my brother (who was her guardian), did not tell her. The family knew that she could not handle the diagnosis and that her quality of life, already bad enough, would probably get worse because she would be so full of fear (she did have some level of senility/dimentia). I believe that Marc Klaas has assessed the situation with BD and has decided that the best course of action is to give her hope that Hailey is still alive. He realizes she still has feelings for SA and it sounds like he is just accepting that without judgement.
God bless Marc, his organization, and all the other organizations and the general public who are helping in this search.
