Tonight’s episode of This Is Us is quietly perfectIf I had to pick an episode of This Is Us to live inside of, it would be this one. Like many of the best episodes of This Is US, “Sometimes” doesn’t play into the stereotypical image of the show as a corny, tear-jerking family drama full of big speeches and histrionic moments. Instead, this is an episode built around quiet interactions, nuanced performances, and grey areas. After hiring a Vietnamese villager named Bao (Dustin Nguyen) to drive him back to his camp, Jack agonizes over whether he’s put his safety in the hands of a good guy or a bad guy. When Jack finally asks whether he’s Viet Cong, Bao simply replies, “Sometimes.” It’s the word that gives the episode its title and one that encompasses the fact that the truth is seldom black and white. When Rebecca asks an L.A. record exec for his honest feedback about her demo, he tells her she’s “Pittsburgh good,” which is both a compliment and (more so) an insult. Rebecca decides to leave L.A. and return to Pittsburgh in part because she’s genuinely fallen in love with Jack and in part because she’s failed at her musical dreams. Kevin’s necklace is both a meaningful family heirloom and a mass-produced trinket. Jack is both a strong, empathetic person and a survivor of trauma. So is Zoe.
