Insecure's first and second seasons were fun; we're introduced to Issa, Molly, and Lawrence and get to know them a little, witnessing their very high ups and drastic downs. But season three, well . . . season three gets real. The laughs keep coming (I'll never forget Kelli getting tased at Coachella for as long as I live), but Issa Rae's HBO comedy takes advantage of how well we know and love these characters by now to really dig into their fears and raw vulnerabilities. The season's fourth episode, "Fresh-Like," is the perfect example of this, as it explores just how much Issa has transformed as a character as she goes on a walking tour of Los Angeles with Nathan (Kendrick Sampson). Later developments with his character in particular, specifically about his mental health, serve as yet another reminder that Insecure still has so much to show us.
