Yusuf is one of Barack’s uncles and the Old Man’s half brother. Granny is his mother. He’s slight and wears a moustache. Yusuf insists that the Luo are too stubborn and uneducated, as they won’t adopt Western farming techniques that would allow them to better use the fertile land around Alego, but Sayid insists that Yusuf doesn’t lead by example. In Sayid’s estimation, having been educated in the city and then introduced to the concept of poverty, Yusuf has simply given up and no longer finds meaning in the traditional way of life in Alego.
