His little brother's life is at stake but he wants to remain stubborn and let pride get in the way?
He probably is under the misconception that it's demeaning to his self-respect to take money from a woman who's scorned you. I'm sorry, but no amount of self-respect or ego is bigger than the love for a sibling. Had it been my brother, I would have simply taken it, even begged for the money! Argh...I'm so disappointed in you Amar!
