Korra catches and cooks some fish in the park, where she meets one of Republic City’s apparently quite large homeless population, her first hint that maybe everything isn’t all sunshine and rainbows. She gets hit with a clue-by-four yet again when she runs into a trio of mob enforcers (look, this show has MOB ENFORCERS) from the Triple Threat Triad trying to shake down a local shop owner for protection money.
