Yeah. That's it. Exactly like that.
Since things are a little slow right here i'll throw out an outside the box idea.
Is it possible that Anna was suffering from Stockholm Syndrome?
Some of us believe she was being held hostage in that house? Whereever she went, she had Howard or a "bodyguard" with her (which per se is not so unusual, but heck even Paris Hilton goes out shopping by herself sometimes and bodyguards aren't attached to her hip). Even on LKL she had Howard right next to her.
On this site http://ask.yahoo.com/20030324.html you'll see that the original Stockholm incident took only 6 days. And "small acts of kindness" by the captors are what gives the captor power over the victim. Also violence, threats, duress, etc.
