Keeping Korra out of “After All These Years” makes “Korra Alone” a concentrated dose of pathos. The road to recovery is long and winding and we feel it when the show show fixes its attention on the arduous journey. There’s minimal crossovers from her snail mail correspondence with Mako, Bolin, and Asami; each voiceover pushes Team Avatar further and further apart. Korra can’t even bring herself to write back to the boys, confiding diffidence and guilt to her only female friend. Though Korra’s encounter with Zaheer didn’t directly deal with her femininity, this moment frames the attack in new light. No matter what the circumstances, if a man infringes on a woman, there are shades of the experience that other men just won’t understand. It’s a beautiful, subtle message for the writers to flirt with.
