Which half brother and half sister said this?
OK, there’s Malik, Auma, (older than 0); Mark, David, Abo, Bernard, and George (younger than 0) on the dad’s/African side; 3 wives’ kids.
And younger half sister Maya on the mom’s side (dad Lolo) is Bernard’s age.
Half sister Auma would be the likely candidate due to proximity to older relatives and being older than 0.
Brother could be Malik due to being older; George is the one who lives in the hut.
George is a possibility....
