We are strong (3)

Indulf couldn't bring himself to be serious. His two fathers had the knack to make him laugh.

They also knew that he was capable of handling things by himself, so they weren't really worried. However, their instincts as parents made them guard his back at his lowest point. For that, he would always be grateful.

Indulf was supposed to be the strongest, hence, he requested his sister to train him to be one. Still, he had no pressure to be one, that's because it sort of just happened to him. 

He was in fact, the strongest in between his male siblings, although his sister was beyond his reach.

He had long accepted his fate to his sister.

Elizebeth had given what he wanted. The biggest present. It was a very precious time. She gave him the training that could raise Indulf's strength by multiple levels.
