In general, Xanatos has an odd way of dealing with those he "loves". One example can be found in Thailog, Goliath's clone that he had Sevarius create. While the clone was being grown he had a program playing giving him information about the world and his beliefs. He seemed to have a paternal feeling towards Thailog as, when the gargoyle was kidnapped during his stone slumber, he would not let Owen fire on the kidnappers out of fear of hurting Thailog, and handed over $20,000,000 for his safe return without a second thought. He even showed pride in Thailog's manipulative abilities and genius when he found out the clone had engineered the entire plot to abscond with the money, referring to him as "a chip off the ole block". He even expressed to Thailog that if he wanted the money he would have given it to him if he would have asked for it. However his paternalism seems thin as, when he thinks Thailog died during battle with Goliath, he states that he knew the whole time that a copy (Thailog) couldn't match the original (Goliath), which infuriates Goliath as Xanatos was able to dehumanize a living being to such terms. Though arguably lacking romance, Xanatos asks Fox to marry him on the basis that "it makes sense" because they are genetically compatible, share the same interests, and "love each other" as much as two people such as themselves can.
