You could say he was always that way. The brother I knew growing up was kind, loving, wanting to protect me. He was like a father to me, but there were moments when he suddenly wasn't that brother. It scared me.

[And now he was always that brother, willing to fight even his sister for his goals. She shakes her head, trying to clear away some of the negativity.]

A lot of things happened, it'd take some time to explain, especially when you're likely to have more questions the more I say.
