Some Make It, Some Don't
Dawson (Monica Raymund) and Casey (Jesse Spencer) deal with legal matters in hopes of remaining Louie's legal guardians. Severide (Taylor Kinney) continues in his efforts for a bone marrow procedure to help Anna (guest star Charlotte Sullivan), but when things don't go as planned, he finds himself slipping back into old habits. Meanwhile, Brett (Kara Killmer) opens up to Dawson and members of Firehouse 51 become competitive, much to the dismay of Chief Boden (Eamonn Walker).
