Ehh Geon is not that bright but I can't blame him for the line that the boy is a perfect mix of him and Sohm. I mean, he's a perfect copy of his dad while Sohm is a perfect copy of his mom. Maybe he expected the kid to look exactly like one of them instead of a perfect mix of them both (which adds to the weirdness as he was their kid and not their little brother).
