By offering Elise’s prayer book to Nadia, Luke suggests he wants to make amends. Indeed, their conversation has thus far been tense, and Nadia has been relatively combative. Suddenly, though, Luke disarms her by giving her the prayer book, an object fraught with her mother’s memory. It’s worth noting that Nadia’s eyes fill with tears as she sits on Luke’s bed, since she didn’t even cry at her mother’s funeral. This suggests that Nadia feels close enough to Luke to show him her grief. Since Nadia avoids letting others know how she’s feeling internally, this is a rare, candid moment.
