The reason what follows is a case is that there is already a curated collection resulting from the inquiry. In order to become a case such a collection needs to be given a form appropriate to the determinations, configurations and assemblages of the actual, in this instance of bios. Ordering this multi-step process might be called syndialepsis. Syndialepsis  differs from metalepsis in that the form of intervention consists in an act of joint evaluation leading to a judgement.
 Marcus Aurelius, book 1, chapter 10: "[What Aurelius learned:] From Alexander the grammarian, to refrain from fault-finding, and not in a reproachful way to chide those who uttered any barbarous or solecistic or strange-sounding expression; but dexterously to introduce the very expression which ought to have been used, or providing confirmation [syndialepsis] about the thing itself, not about the word, or by some other fit suggestion."
