One of the things I like about this show is that is that it takes someone who's made some bad choices and is looking for a fresh start and gives them a new identity. Sounds liberating right? You've just gotten rid of your past. Problem is, it's not really a fresh start. You've taken over the identity of someone who has their own character flaws, much worse than yours, their own problems, etc. You can start somewhere else but you can't completely start over. You can ditch your own past, but your still stuck with somebody elses.
