Madame Rosa is in exceedingly poor health and begins experiencing dementia, at times having flashbacks to the Vel d’Hiv roundup and falling back into the belief that she will be arrested by the French Police and sent back to Auschwitz. Mr. Hamil also begins to have dementia, taking solace in the writings of Victor Hugo. After she has a bad fall on the stairs, Dr. Katz informs Momo that she has many health issues including hypertension. She refuses to be hospitalized. Momo believes she should be euthanized. When told by Dr. Katz that euthanasia contradicts French values, Momo replies he is not French and that Algerians believe in self-determination. Momo's father, who spent time in an asylum after murdering Momo's mother, returns to try to collect Momo, but Madame Rosa tricks him into believing that she raised him as a Jew and he suffers a fatal stroke. Momo is with Madame Rosa when she retreats to her Jewish space under the staircase to die, and is discovered with her body three weeks later. Afterwards, he goes to live with the film editor.
