“Hearing that his brothers are dead, Bharata will indeed die as well. And seeing Bharata dead, Shatrughna will also no longer be. And seeing their sons dead, there is no doubt that the mothers - Kausalya, Sumitra and Kaikeyi - will then no longer be as well.” (Hanuman, Valmiki Ramayana, Sundara Kand, 13.26-27)
