If he doesn’t share with you neither of your parents, he is a total stranger to you and you should observe hijab from him from as early as 11 or 12.

I was wondering if my 13 year old step brother is my mahram until he turns 14/15? because currently I do not wear a scarf in front of him because i read it is only when he reaches puberty or the age of 15 that he becomes non mahram. is this true or even do i still have to observe hijab even though he is 13?
