Re your message on my talk page I can quickly reference MOS CONTRACTION but I m not sure how you are defining prose Generally speaking I try to avoid expanding contractions in things like articles recapping episodes of shows etc My understanding of this issue is based on another MOS section indicating that contractions 1 do not sound encyclopedic and 2 are less clear in meaning See also MOS ABBR from which I quote A contraction is an abbreviation of one or more words that has some or all of the middle letters removed but retains the first and final letters e g Mr and aren t Missing letters are replaced by an apostrophe in multiple word contractions Multiple word contractions should not be used italics mine Thank you The first link was the one I provided The second was more clear
