(Twin) brother by another father.

I am not even going to bother moving beyond fact in this case: a woman had sex with her boyfriend, and then cheated on him soon after, leading to the one-in-a-million (seriously, 1/1,000,000) outcome of a set of twins with different fathers. The boyfriend has been told of the infidelity and has agreed to raise both boys as his own, despite being biological father to only one. Of course, since modern news stories only ever seem to hamper progress toward social equality, the family is black, the parents unmarried, and the lot of them live in good ol' Texas. America, fuck yeah!
