The love Maris showed Esme was nothing but a conspiracy and plot the father and son played to fool and kill her.
But it was not that easy, Maris had not thought he would fall in love with her and when he did it came with the wrath of his father, who pressed him to kill her.
He was punished by his father to kill Esme with his own hands, though he tried all the things he could to get it done but he was never able to kill her.
Though he was able to bring her and the child close to death. Thoth saved them both, and after that, everything Maris did make them both only stronger.
The baby grew inside Esme's womb incredibly fast getting stronger, every poison Mairs used to kill her made her get stronger, making him fear his life, and was left with no choice but to ask for help from the stranger to bring her close to her demise.
