So if we toss out notability, I can have a bio if I can prove I exist through a reliable source?
What "complete set" are you a part of that we have existing coverage of? The context we're discussing here is a situation where it's not there's no dispute at all about whether we should have an article about a TV series _as a whole_, but it's in question whether we should have more specific articles about individual episodes within that series.
Personally, I think it's entirely reasonable to have our criteria for inclusion be transitive. When an article becomes very large we split it into smaller sub-articles, it would be silly and counterproductive if we then turned around and deleted the smaller sub-articles because they're too specific in their focus.
