When working on a new idea, before you write anything it's obviously best to structure out the episode so you're not writing blind.
My question is: do you have to structure episodes for the series, or just for the episode you are going to write?
The reason I ask this is because I have ideas for four episodes and am working on the remaining two, but is it best to make sure you have a possible series in you before you start writing?
Thanks in advance fellow comedy nerds.
