With a sure-to-be legendary Episode 6, "The Bear" shows us what life was like for Carmy, Sugar, and the other characters in the Berzatto family's orbit. It's Christmas Eve, and Carmy is home to celebrate with his mother's traditional Italian seven fishes. The customary seafood dishes (and bears) become loaded metaphors. Stevie (John Mulaney) gives a blessing about love demonstrated through service and sacrifice, and the guests debate whether bears are empathetic, aggressive, or both.
For the Berzattos, it's both. A well-intended but unstable Donna loses her cool more than once. She melts down as she violently grabs Sugar by the chin, then again at dinner when she doesn't feel properly appreciated and her daughter dares ask if she's okay (this informs an earlier present-day scene between Carmy and his sister). Finally, Donna drives her car into the house as Sugar watches in horrified disbelief. It's clear that she and Sugar have a toxic relationship in which the child feels more responsibility for the well-being of the parent, rather than the other way around.
Carmy, meanwhile, is more focused on Mikey, who's locked in an escalating fight with Bob Odenkirk's Lee. Though he won't fully realize the seriousness of his brother's illness until after his death, it's becoming apparent to Carmy that Mikey — and his family — are plagued by generational trauma. His cousin, Michelle (Sarah Paulson), sees it, too, and offers him refuge. He's left to decide whether he should stay and try to fix his family or whether he's better off alone and away. It's a question he's still wrestling with leading into the finale.
