Caroline is a minor character in the TV Series. She is a Wife.
In the Present Edit
Caroline attends to Naomi Putnam while she acts out the birth of her Handmaid Janine's child. She gathers around the food table with Serena Joy and Leah, and asks June about the progress of the birth. She objects to Leah offering June a cookie, stating that "it's bad for Handmaids" and, as June walks away, refers to the Handmaids as "whores".
Shortly after the birth of Charlotte (whom Naomi names Angela), Caroline visits Naomi along with Serena Joy and several other Wives.
