Before leaving this stronghold, Jack decided that he was going to send someone back to the normal world. There was still something that he needed to take care of, considering that he had already been away for about two weeks now.
He did not know what was ongoing in the normal world currently considering that there was no connection between the normal world and the stronghold domain. So, other than the fact that he wanted to complete his end of the contract with the shadow organization, there was also a part that he wanted to deliver a few things to Jonathan and Celine's parents.
Of course he wanted them to get stronger. He did not want them to be vulnerable. So, it was better if they got stronger, strong enough to be able to protect themselves, rather than just depending on others.
