Ever wonder how the Cobra Kai crew would handle an outbreak of, um, mononucleosis? No? Well, you’re about to find out anyway. In Season 5 of the series, Demetri (Gianni DeCenzo) comes down with a case of the dreaded “kissing disease.” In an effort to help him get better, his friends — Samantha (Mary Mouser), Hawk (Jacob Bertrand) and Tory (Peyton List) — take matters into their own hands, using a homemade shrink ray to send themselves into their pal’s innards and fight the germs, Eagle Fang style.

Wait, wait. We seem to have mixed up the scripts for Cobra Kai Season 5 with this delightful video of the cast reading Cobra Kai fan fiction. False alarm! None of that happens in Season 5! (Obviously.) But, if you do want to know what happens with Demetri and his encounter with mono, check out the video below to see Mouser, Bertrand, DeCenzo and List act out the fanfic script — and discover just what happens when his friends turn Demetri’s body into their latest fighting ring.

The real Season 5 of Cobra Kai is currently streaming on Netflix. As far as we know, there’s no shrink ray.
