A royal is forced to escape his country after he's been betrayed by his family. It's three parts composition. 
In the first he is realizing he may not ever be coming back and he is overwhelmed by sadness.
In the second part he starts to realize it's not his fault he has to go, he was betrayed by those closest to him.
The third part is full on rage and hoping for revenge.
That was the original brief, but it's applicable for anything with dramatic storyline ending with rage, anger, running away.
