The Prince of Light trailer is so misleading

Prince Rama wasnt exiled by his own brother, his brothers dearly loved him..

His brother, Bharat, wasnt involved in the plot of exiling his brother...
The exile was been ordered by his mother, KaiKeyi since her maidservant manipulated her so Bharat will be crowned as the next king of Adhyoda

In fact, Bharat along with the his brother was with their maternal relatives in that time

Bharat doesnt approve the shit and go to the forest to track Rama down and convince him to go back

Also the brother in that scene is Lakshimi not Bharat
