She shot herself to make it look like she was dead, so he wouldn't try to go back in and find her. She can "live" in V-World for as long as she needs to, trying to figure out what to do with herself, without having to worry about her family's well-being.
Meanwhile, if Amanda is alive, I think it would be interesting if Vergis was the first person to visit her in the hospital instead of Daniel, and they begin an affair from that point on.
Also, I love that Clarice shows a more aggressive side in this episode. She always seemed like the type of character that would whisper in someone else's ear to make them do her dirty work for her, but here she shows that she does have some fangs of her own, and will use them when she needs to. I want to see what happens after she realizes who killed Nestor. (I assume he was still in the car when it exploded.)
