History[]
Due to her failing memory, Mama Coco continuously mistakes Miguel for her late husband and couldn't recognize her daughter. However, despite that, the family loves Coco. Also, because of this, Miguel tells Mama Coco everything, especially his love for music.
She begins forgetting her father and Hector desperately wants to cross the bridge to get to his daughter. It's after Héctor mutters Coco's name that makes Miguel realize that Coco's real father was him and not de la Cruz and causes them to realize that they are family.
However, when Miguel returns and plays the lullaby version of "Remember Me" to Mama Coco, she immediately remembers her father and finally recognizes Abuelita as her daughter Elena. Mama Coco begins reminiscing that song and her mother and father singing such beautiful songs. Luckily, with Coco remembering her father, Hector is saved from the Final Death.
A year after the events, Coco passed away due to her age, and is reunited with her parents in the Land of the Dead.
