Here is a list of the main characters on Dead Like Me along with some information about them.

Georgia "George" Lass, played by Ellen Muth, was an 18 year old college dropout on her first day of work at Happy Time Temp Agency when she was hit by a toilet seat that fell from a space station and died.  However, instead of moving onward and upward, George joined the ranks of the undead as a grim reaper.  In the beginning of the show, George was lost, confused, and very angry about her life ending so early, but she eventually matured and came into her own as a person.  When she died, George had no idea of where her life was going (nowhere, apparently) and was in the transition between child and adulthood that everyone has to go through.  She had never been on her own and had to learn very quickly how to make her way in the world, even though she was no longer living.  She returned to Happy Time and got a better job as Millie than when she was George (the living did not see her as she looked before she died), and she learned to take responsibility for her actions as a reaper.  She still maintained her rebellious nature, but learned to control it and not let it interfere with the work she had to do.  George was always drawn back to her family throughout the show and kept going back to check on them, or calling their house just to hear them talk.  Rube told her it would just end in heartache for her to keep seeing her family go on without her, but George couldn't help herself.  Even though she could no longer be a part of her family in any sense of the word, George found a new father figure in Rube and a mother figure in Delores, and both did their best to look out for her as she found her way through her afterlife.

Mason, the eternal screw up, who died in the 1960's after drilling a hole in his head trying to reach a permanent high, was played by Callum Blue.  Mason's afterlife probably resembled his actual life more so than any of the other reapers, as he never appeared to learn from his mistakes or change all that much.  He was all about alcohol, drugs, and money, and the reaping usually took a backseat to his other hobbies.  However, Mason could be a sweetheart when he wasn't acting the part of the idiot, and he was affected emotionally by more than one of his reaps.  And no matter how little faith everyone else held in Mason, he always got the job done.  As for his part in the merry band of reapers, Mason's favorite pastime seemed to be annoying Roxy and seeing how far he could push her before she exploded on him (lucky for him reapers heal quickly).  He also acted as sort of a big brother to George (even though she was way more mature than him), and he had a huge crush on Daisy.  Although nothing really came of that relationship, Mason did truly love Daisy and he wanted to become a better person for her.  As much as the other reapers were annoyed and sometimes appalled by Mason and his various antics, I believe that they all loved him in their own ways and the group would not be the same at all without him.

Mandy Patinkin played Rube, the leader of the group of grim reapers focused on in the show.  He had been dead for longer than any of the others and thus had a certain wisdom of the ages that they all looked up to.  He sort of adopted them all as his "children" and tried his best to look after and guide them through their afterlives.  Even though he was the leader and distributed the post-it notes of those that were going to die to the other reapers, Rube was only a little less in the dark about the whole thing as they were.  He didn't know what happened after death anymore than they did and only knew the information he did from experience.  Not much was known about Rube except that he loved Der Waffle House and food until the second season when his past was revealed.  Before he died, Rube was married and had a young daughter named Rosie.  He found his daughter again right before she was going to die and revealed himself to her, breaking one of his own rules, and got to say a proper goodbye.  His character always had a lot of heart and you could see that he truly cared about all of the other reapers, though he had a strange, tough-love kind of way to show it.

Roxy, played by Jasmine Guy, died in the 1980's when she was strangled with her own invention: leg-warmers.  She was the muscle of the group and had a very quick temper and a matter of fact attitude.  In the first season, Roxy was a meter-maid along with her reaping duties until she became a full-fledged cop.  Roxy never gave too much away about herself, but she was really good friends with Rube and always confided in him.  She was kind of his second in command and was left in charge whenever he had other things to attend to.  Roxy and Mason had a strange dynamic in that he annoyed the crap out of her and she barely seemed to tolerate sitting at the same table as him, but I think that they were really good friends underneath it all.  Roxy was like that with everyone though, keeping them at a distance, but helping them out when they needed it.  She didn't really advertise her friendship with everyone else, but they all knew that she would be there to take care of them when it counted.

Laura Harris played Daisy Adair, an actress who died in a fire on the set of "Gone With the Wind".  She was transferred to Rube's posse from New York because she was a trouble-maker and set up elaborate schemes to swindle the relatives of dead people out of money.  When Daisy first came onto the show, she was quite the air headed bimbo who's favorite pastime was recounting the tales of her sexual exploits throughout the years.  Rube forced her and George to live together even though neither one was happy with the arrangement at first.  Once Mason gave them his house though, the two came to a sort of truce and began a friendship.  For all of Daisy's self-confidence and outward poise, she felt very alone and insignificant inside.  Her last words were "Why has no one ever loved me?", and after reading them Mason began to see her in a new light and fall in love with her instead of in lust.  Daisy tried her hand at religion for a short while after she stole a cross from a dead woman, and it seemed to ground her character, even though she gave it up quickly.  Daisy was in constant search for who she was and what her purpose was throughout the show, even though she could act like everything was fine.  Her brief relationship with the abusive Ray may have just been the kick in the pants she needed to figure that out for herself.

Delores Herbig, as in her big brown eyes, was George's boss at Happy Time Temp Agency and was played by Christine Willes.  Quite an oddball character, Delores had a tendency to say whatever was on her mind without a filter and always with a smile on her face.  Though she didn't much like George when she worked at Happy Time, she took Millie under her wing and became good friends with her.  Delores loved working at Happy Time and also loved her old, sickly cat Murray.  She also loved cleaning and organization, and even had a website called "Getting Things Done With Delores" complete with web cams in her house, which was kind of creepy to George.  Even though she thought that Millie was a recovering drug-addict who spent too much time at the doctor's office (lies that George told to get out of work early), Delores looked to Millie as her second in command and confidant.  When George left Happy Time in search of a better job, Delores was kind of heartbroken and saddened.  She eventually took her back after George helped her out with Murray at the vet's office, and the two's strange friendship started up once again.

Cynthia Stevenson played Joy Lass, George and Reggie's overbearing and crazy mother.  She greatly disapproved of George's decision to drop out of college and thus forced her to get a job at Happy Time.  When George was killed on her first day of work, Joy's world fell apart.  She still had her husband and other daughter, but losing a daughter just broke her.  She tried to keep up appearances, but inside she didn't know how to deal with her grieving.  Joy became overprotective of Reggie and tried her hardest to get her to open up about her feelings, but the family had never been very big on openly discussing things.  When her marriage fell apart, Joy began to start anew and get her life back on track.  She looked for apartments in the city, started dating again, and even tried to get back in the work force.  It would still take a long time for Joy and the entire Lass family to come to terms with George's death, but they were on the mend by the end of the series.

Reggie Lass, played by Britt McKillip, was George's younger sister who was deeply affected by her sister's death.  Before she died, George payed no attention to Reggie and acted as if she wasn't there more often than not.  Reggie was already an oddball before George died, but afterwards, she became even more so.  As a tribute to her sister, Reggie collected as many toilet seats as she could and hung them from the branches of a huge tree in George's honor.  George left Reggie many presents trying to make up for the way she treated her while she was alive.  Reggie was convinced that George was still around, and she was right, but her parents thought she was crazy and took her to a child psychologist.  Reggie's life was shaken even further when her parents got a divorce and her mom began trying to sell their house.  Reggie was just a lost little girl who had no one to talk to about her problems and issues, so they were kept bottled up inside.  Joy tried to get Reggie to come out of her depression and protect her like she couldn't protect George, but it didn't always work.  Reggie tried her best to cope with losing almost everything in her life, and knowing that George was watching over her (literally) helped her out a lot.

Played by Greg Kean, Clancy Lass was a college literature professor and George and Reggie's dad.  He was having an affair with one of his students throughout the entire show, even though in the pilot it was a male, and in the series it was a female.  Once George died, his and Joy's marriage fell apart and he moved further and further into his affair as time went on.  The two eventually divorced and he moved into an apartment.  He and George had been very close when she was younger, but drifted apart as she grew up.  Both regretted that their friendship ended, but neither knew how to get it back.  Clancy never really had the same relationship with Reggie and didn't know quite how to relate to her after George's death and the divorce.
