As per Ramayana, Rama had 3 Brothers, Bharata, Lakshmana and Shatrughna.
When Rama is exiled,Bharata goes to Rama and asks him to come back to Ayodhya but Rama refuses. Though deeply disappointed, Bharata returned to Ayodhya after receiving a promise from Rama that he would return promptly at the end of the fourteen-year exile and ascend the throne.
As per Hanuman chalisa verse, तुम मम प्रिय भरतहि सम भाई (meaning, You are as dear to me as my brother Bharata) which clearly shows deep Love between Rama and Bharata.
Lakshman is the younger brother of Rama and close companion of the god Rama, Lakshman serves Rama and Sita reverently during the exile.
Lakshmana is specially attached to Rama, and when Rama marries Sita, Lakshmana marries Sita's younger sister Urmila.Later, when Rama goes on exile for fourteen years on the insistence of Kaikeyi, Lakshmana leaves his wife Urmila and joins Rama.
Lakshman also built hut for Rama and Sita to live in Panchvati, as per Wiki Link.
This indicates how close and dear Lakshman was to Rama.
Is there similar incident/occasion exist in Ramayana that shows Love/closeness between Rama and Shatrughna?
How was the relationship between Rama and Shatrughna?
