The Office: New and Old Characters

Toby Flenderson: He was the Human Resources Representative from Corporate (Seasons 1-4). Michael dispised him. He once refered to Toby as "everything that is wrong with the paper industry". Toby was a nice guy and he always put up with Michael's obvious hatred of him. Toby had a bit of a crush on Pam Beasley (to be discussed in detail later) which might have prompted him to leave Dunder Mifflin and head for Costa Rica. Toby is a divorcee who has a young daughter named Sasha.Holly Flax: She is new to Dunder Mifflin. She is replaced Toby Flenderson at the end of Season 4. She is, as I said in a previous post, much like Michael. Because she is new not a whole lot is known about her. It seems that she does like Michael in return though. So far, things are going well between Michael and Holly and that is thanks to Jim Halpert.

Karen Fillipelli: Karen worked at the Stamford branch of Dunder Mifflin (along with Andy Bernard). Karen and Jim Halpert had a relatively short relationship in past seasons. She now is the branch manager at the Utica branch.

Others you might hear of:

Todd Packer: "friend" of Michael Scott. He is a traveling sales representitive for Dunder Mifflin. He is a bit rude and vulgar.

David Wallace: He is the Chief Financial Officer. He rarely appears.

Mose Shrute: (seen above ^) Dwight Shrute's cousin who works and lives on the family beet farm. He has few if any speaking roles. He is usually seen being awkward and timid in the background.
Roy Anderson: former fiance to Pam Beasley. He worked as a dock worker at Dunder Mifflin. They had a very long engagement (which irked Pam). He finally decides to set a date but shortly after they break up. Roy tried to fix things but in the end he encouraged Pam to date Jim.
