Duke Olivier observed his closest knights' reaction to seeing Dimo again and was relieved that they were genuinely glad Dimo was safe and sound.
[Dimo gained some weight again.]
The Duke also noticed the change.
[I thought something was wrong with his appetite because he still missed his mother. But Sonia must have been giving him glares or treating him badly behind my back, so he didn't eat much. The difference in his height and weight is very much noticeable ever since he began staying with Her Imperial Majesty.]
Duke Olivier was even more assured that for now, it was best for Dimo to stay in Valeria.
He didn't need to worry that Dimo might not be treated badly since just more than two months of Dimo staying in the Magic Tower gave such a clear difference both in the child's physical appearance and mood.
