Based on Fiona’s assertion that she knows what she’s doing and Marcus’s ensuing conclusion that she actually doesn’t, Marcus begins to critically assess his mother’s decisions. This signifies his developing sense of individuality and increasing desire for autonomy. His plea to continue visiting Will coupled with his tactical declaration of needing a father highlight the extent of his longing for a male role model and practical guidance, which he feels his mother cannot provide. This desperate appeal impacts Fiona deeply, pointing to the deep emotional currents underlying their relationship. Marcus’s “victory” in this argument represents a significant moment in asserting his needs and shaping his identity.
