Children collecting fireflies in the Glades stumble onto the corpse of US Navy recruiter Doug Preston, who was dumped there. Jim is more surprised when his team is given a 'forensic nurse,' to Carlos's delight none other then his lover Callie, which proves uneasy for both of them, especially as she's still jealous of the Chicago ex. Suspects include Frank Morgan, whose son volunteered and died in Afghanistan, and Doug's ex, an alcoholic who keeps secrets about everything, including boyfriend Bradley, and Doug's baby son, who went missing very recently.
