I agree. He does care for his brother but not sure how to show it. Instead you he wants to keep him close to where no one else can see or have him. That's my theory
good theory. i just had a feeling that he was possessive for how he acts.
I disagree. His brother probably noticed the throbbing and chained him up so he didn't do something even worse to himself
question to that: why would he chain his brother up just because of pain in his chest? he could of just locked the doors to make sure his little brother didn't leave the house/room if it was just because of the throbbing in the chest. when i see chains in usage, if it ain't for S&M play, then its used by a possessive who wants to keep something or someone locked up to themselves.
forgot to input 'person' between possessive and who.
what a possessive brother.
