Do you absolutely have to have a B-story in a half-hour sit-com?
I wrote an episode for a TV series, but now realize I didn't include a B-story. I had so much fun writing that I didn't even think about it. I found a handful of episodes from other series that have little or no B-story, but they're rare. I have no problem including one, I just don't have one, and I wanted to be certain before investing the time and energy. Were I writing this in any other form (stageplay, short story, et. al.), I wouldn't include a B-story because it isn't necessary, but almost every TV sit-com episode has one.
Do I need to include a B-story, or is it fine without one? Thanks.
