"F-father?" Perseus said while shivering as he did not trust his own father to spare his life under such circumstances.
Although they were a family, ever since they were children, both Sophia and Perseus realized the fact that they were merely assets in the Olympian cause and not actual family members.
Their mother was voiceless and only a breeding partner for their father because of her good genetics, while their father's love for them was conditional on their use to the family.
Because Perseus showed competence since young age and Sophia was chosen as the Champion Of Poseidon, Escanor showered the kids with a bit of his love and attention, however, this did not change his base feelings towards them.
For him, his children were no different than an important underling or a disposable asset, as at the end of their use-case Escanor was more than willing to discard them without any attachments.
