Mr White was proud and also happy about David overcoming the instinctive fear but he didn't let it show on his face.
He knew that during the fight between he and Adeola's father, the prowess they had shown wasn't something an ordinary Spryher would see and wouldn't be intimidated.
The energy waves of overwhelming power and destructive they had released that day was great.
It wasn't that the heart was weak, it was somthing to be expected since the hierarchy between them showed too much of a difference on the food chain.
It's the instinctive fear a small animal feels when encountering a lion. It was from the gene and had nothing to do with how how strong your heart is.
Normally, he had expected David to take sometime to overcome the fear and then recover after a few days of interaction.
Since it would fade overtime, but David had surprised him once again by how strong his will power was.
