Celia is Ingrid’s best friend and an acquaintance of Henry. When Celia finds out Clare is dating Henry, she warns Clare that Henry broke Ingrid’s heart and often mistreats his romantic partners. She remains skeptical of Henry, but she is kind to Clare whenever their paths cross. Clare invites Celia to her and Henry’s wedding, and Celia attends despite Ingrid’s anger toward the situation. Celia also later attends the New Year’s Eve party that occurs on the last night of Henry’s life. At the party, she expresses her regret to Henry that his feet were amputated without pitying him, for which he is grateful.
