A talk show is scripted to promote the guest and discuss topics with which the guest is comfortable. Imagine your protagonist on the Ellen Degeneres Show (or The Late Show With Stephen Colbert - whichever show you're familiar with). What questions would be asked of your protagonist? What funny anecdotes would your protagonist share? Write down the reactions of both your protagonist and the host.
Set a timer and start free-writing from one of your character's perspectives. Try to really get inside their head - what do they want, what ticks them off, what do they feel passionate about? Are they writing in a diary, telling a story to a friend, or dictating a formal letter?
