Minor plot hole in s4 E4

Nolan and Bailey argue about who’s better between firefighters and cops. They decide to go over story’s to see who has better ones. And for some reason Nolan…. Has a problem coming up with one. My man went on a recon mission in Guatemala, got a hit put on him by a gang, watched his captain die, got framed by a crooked cop, and uncovered a money laundering scheme in the department. All of this somehow slipped his mind.
