Saurin's Links
At first, he was afraid that Siegfried would soil Elabelle, knowing of his poor background. However, after coming to know this man personally, he became fond of this individual. And to his surprise, he and his newfound partner, fight quite well together... like an even pair. Their combat styles seem to compliment.
Siegfried used to be jealous of Saurin only because of his title and his easy life - even more because the Princess was much closer to Saurin. However, once had got to know this fine man, they became closer than ever.
Saurin doesn't really have any bias towards Roy. If his Princess supports him greatly, then Saurin will only do the same.
He does find Roy amusing at some points. The man appreciates his leadership abilities, even if he finds him goofy or lazy at different times.
Saurin clearly continues to be confident, believing that Roy couldn't stand up to the mage's powerful tricks.

Saurin can't necessarily say that he's excited for Elabelle giving birth to her children. But because of the Queen's busy schedule, he sometimes has no choice but to tend to En's needs. Siegfried may be a better uncle or caretaker than he, but Ardal finds it much easier for him to use his magic to summon whatever the boy wants.
Since he was exiled, Saurin cannot help but be concerned for the boy. He will try his best to give En what is truly needed, especially if it's under Queen's commands.
Saurin has always been like an uncle to En, and a fun one at that! En's favorite memories of visiting his mom's kingdom was to hang out with the sorcerer, watching his amazing skills while at the same time getting a bunch of treats! He was one of the people En went to first when he was exiled, and he was also the one to help teach him how to hone his swordsman skills.
