Johnny falls back on a gurney and goes into a vision. A crash team tries to revive him, and shocks his heart. Pratt, Walt, and Sarah watch in non-vision land as Johnny's body jumps and arcs on the gurney. Back in vision land, the crash team gives up and pronounces Johnny dead. The guy calling the death sounds like Comic Book Guy from The Simpsons. Worst. Code Blue. Ever. Cut to the morgue. Johnny watches his own body being autopsied, which is pretty fucking creepy. The coroner says that the virus had spread to all of the major organs. Now Johnny is in the hospital conference room and he sees the word Chloroquine written on the whiteboard. Navarro shows up and announces something about the Chinese scientists realizing that the only people who were surviving the virus were those who were also being treated for malaria, so Chloroquine, an anti-malaria medication, proved to stop the virus.

Johnny pops out of the vision and runs down to the CDC. lab. Navarro is pissed that Johnny just exposed her whole team to the virus. Johnny ignores her and grabs The Big Book of Nasty Stuff. He holds a section of pages and divines which page to look at. He points to something on the page and tells Navarro that it's her virus. Pratt reads the name of the virus aloud. Navarro says there's no cure for that virus. Johnny writes Chloroquine on the board and explains that there have been survivors of the virus in China. Before he can finish, Johnny collapses onto the floor.

We fade up on a hospital room. Johnny is lying in the bed, just waking up. He sees Walt, Sarah, and J.J. sitting there. Johnny grabs J.J., who is right next to the bed, in a huge hug. J.J. seems a little taken aback. Walt hugs Johnny too. Aw. Walt says that Johnny's been unconscious for three days. Pratt explains that the CDC was able to administer Chloroquine and stop the virus, thanks to Johnny's assistance. Sarah nudges J.J., who shyly thanks "Mr. Smith" too. Johnny tells J.J. to call him Johnny. Walt says he knows what J.J.'s science fair project will be next year, and then supplies, "Skydiving!" Everyone laughs. Sarah silently mouths "thank you" to Johnny, who smiles back and nods.

Next week: Johnny hooks up with a lady, and starts having visions that they are both going to be killed.
