Merci Suárez Changes Gears

One of Merci’s eyes is amblyopic, meaning that it sometimes moves involuntarily. This condition flares up when Merci is stressed or upset, and Medina makes repeated reference to this phenomenon throughout the book. The medical condition therefore symbolizes Merci’s struggle to find her place. Her condition stigmatizes her and marks her as different, and even becomes the basis of some of Edna’s bullying taunts. Its presence during her most trying moments heightens the drama and struggle of those moments. Just as Merci does not let her eye prove to be a hindrance, she also overcomes the obstacles presented to her throughout the narrative. 

Lolo’s nickname for Merci is a recurring motif within the narrative. For much of the narrative, the name “Preciosa” highlights the unique intimacy of Merci’s relationship to her grandfather: Through his patient nurturing and affection, he makes her feel loved and seen in a way that no other family member can. However, there is also a point in the narrative when Lolo insists that Merci will always be his preciosa, which makes Merci feel constricted and bound to a childish identity.
