TV Characters We Want Back on Their Shows

TV characters come and go, but every once in a while, a character we were sure we'd seen the last of comes back. Last week, it was reported that Criminal Minds had rehired A.J. Cook, who played Agent J.J. Jareau since the show's beginning. In the spirit of that great news, we present a few more beloved TV characters that we (and our users) would really like to see back on their shows.
