Forming every paragraph of dialog into perfect rectangles is way more extreme than just avoiding "widows". The usual term for this is "full justification" and typographically when it's done it's typically through word spacing and letter spacing. Full justification in monospace through word choice (which is what the Ares Luna article is about) is bonkers, but I can't see that happening for TV dialog.

I've sometimes heard "orphan" used to represent a single word left alone on its own line at the end of a paragraph, but the terms are often confused and Carter could have used "widow" in that sense.

I'm curious to see what the hard-copy scripts actually looked like. The soft copies I've seen aren't particularly idiosyncratic but maybe they've been normied: https://www.dailyscript.com/scripts/the-x-files_production.h...

Widows are when the final line of a paragraph starts the next page. Orphans are when the first line of a paragraph ends a page.
