Does Sheldon have a brother and if so what is his name

He has a twin sister and a brother. I don't believe they have 给 his name yet

Yes, he has a brother, as mentioned in the latest episode. However, I don't recall a specific name.

你 know, to be honest, i don't remember him mentioning a brother. but i do know he has a sister. in the 圣诞节 specail (spoiler alert) she has a baby :3
