The next morning, Don's on his way out the door; the kids say goodbye, and Betty tells him they're going to the community center to watch the pool being filled. They share an affectionate smooch, and then Don leaves. Later, Betty's doing laundry as she calls to the kids not to jump off the bed. Given what you're about to do, I'd suggest they hide under it. We see the clock read one, and Betty is now sitting having a cigarette. Oh, dear. I can only think that this quick shot was included to demonstrate that she's back to sitting and smoking and letting herself go. And I'd express the hope she's more at peace with it now, but that theory's about to be, um, shot down. Cut to outside, where we see her still smoking and giving the flapping pigeons an appraising look. She then raises the kids' BB gun and starts shooting away over the neighbor's frenzied objections. So, what time's therapy tomorrow? Seriously, aside from the obvious revenge against the neighbor, I think she wasn't trying to hit them, but to scare them into not coming back, thus metaphorically giving herself, "Birdy," freedom, especially given the reversion into her housewife's identity. "My Special Angel" plays into the closing credits, and whatever the reason for that ending? Awesome.
