Tony and Michelle are both back this season and married. As is Audrey. Chloe is the girls next door type who will shoot if she has to, hell this season it will be more like when she wants to.
I don't understand why they had to bring Audrey back. Couldn't she have just gone away quietly? She thought Jack was dead, leave her alone and let her mourn. Plus, I don't like her character. :(
Chloe is NOT the girl next door. More like the obsessive/compulsive neurotic next door. Exactly the kind of person I'd expect at CTU :)
