Usually, when a television drama that has been running for four seasons reaches its penultimate installment, there is a sense that things are wrapping up. Of all the Ts yet to be crossed in My Brilliant Friend, Lenù’s obsession with Nino is the most pressing. She is finally on the other side of her relationship with him, but if it’s frustrating to see Lenù dressing up for his visit and worrying about his feelings for Lila (and vice-versa), it also makes sense.
