The cenote scene represents how Ernesto is willing to sacrifice everyone around him even and for success.
Her father David got married again to Christina McLarty in 2015.

Likewise, Ernesto disguises his attempts to stop Imelda and recover Héctor's photo as dancing and performing, complete with turning his scream of pain into a hearty Mariachi grito when Imelda stomps on his foot to set herself free and steal back the picture.
This shows he's being forgotten, and once he is remembered once again by the Riveras, his bones revert to white, he gains a pair of shoes, and his clothes are good as new.
This was met with criticism from the community in the United States.
