Introduce characters

Today, i watch epsoide one for IT crowd 

IT crowed，there are three main characters, Maurice Moss，Roy Trenneman，Jen Barber. In the epsoide one, Director introduce these characters separatly.

The title of epsoide one is Yesterday's a jam.
At beginning, Jen Barber go to manager room to interview a job, Denholm ask Jen, which experience with computers she has. Jen say she can sending e-mails, receiving e-mails, deleting e-mails and so on. Finially, Jen's job is IT manager. Through these diolgue, we can find in fact, Jen and Denholm don't understand the knowledge of computer.

Denholm say Jen's colleagues are standard nerds. Then location change to IT department. 
Maurice Moss say a lot of professional words，and he find the other people has already has hung up the phone. 

Roy Trenneman is easy to angry,because he think they looks like Yesterday's  a Jam,  becasue other people 're pally-wally when there's a problem with their printer but once it's fixed They toss Maurice and Roy away like yesterday's jam. In fact they don't know how to communicate with other people.

IT crowed use dialogues to introduce characters. For my script, Sara love Jim, so her dialogues is about how to care about Jim's work and life.
Tony is a manager, So his dialogue is about how to sent case to Jim.
Jim is a worker. So his dialogue is about how to show his skills.
