This one is a dud, and a flashback dud at that. Crockett and Tubbs chase a dealer named Ricque and Sonny shoots him down. The dealer's girlfriend Angel manages to cap Sonny, sending him to the hospital.
And then we get the cast memebers watching Sonny in the bed and thinking about prior moments, which we see in flashback form. Ho hum. And Tubbs tracks down Angel. No surprise.
Big spoiler - Sonny makes it! Wow, and who would've thought it possible, unless they realized the season wasn't over, he's the show and they wouldn't kill him off in a flashback theme.
