Reid also goes, but including him would impede the catchiness of the title. In an odd turn for Criminal Minds, "Lessons Learned" is about the BAU trying to thwart a terrorist attack, because apparently their purview consists of 'all crimes'. Prentiss must prove her mettle to stand shoulder to shoulder with the big boys, and she does it...supposedly. Ronnie and Jazz mourn a beloved Criminal Minds supporting character, tease a summer project that might not actually happen, and as always circle conversations back to Spider-Man.
