She found the season premiere to be "pretty boring", but called "Jus in Bello" to be "one of the best episodes of the year, maybe even of the show itself", because it begins with an "epic battle" setting but still "focuses on the personal level of the Winchesters and the people around them". Also praised was the character growth for the brothers, such as Sam's exploration of his darker side. Because Dean is usually portrayed as having a "tough, bravado filled exterior", she liked to see Ackles "go deeper" during his character's many "earnest conversations" with Sam.
