His mom is the granny’s daughter. So that is his biological grandma.
Meaning that he is the son of grannies daughter. So they are related. Grannie isn't related to the step dad.
but didn't the aunties said that his dad (the granny's son) grew up in the island?
Maybe they both grew up there. My parents are from the same village so it's not that much a stretch.
What does he mean when he said "grandma doesn't have a son, she have a daughter" I'm kinda confused
