Lord Rama performs Ashwamedha Yagna, the same Ashwa (Horse) comes into the hermitage of Valmiki, thus the twins happen to read the declaration of Lord Rama inscripted on the golden plate which was hanging on the forehead of the Ashwa and considers that this would be better chance for them to question Lord Rama regarding Mata Sita and to argue with him regarding Dharma.
