Heartwarming / Maria Campbell of the Astral Clocktower

• After Maria realizes that Katarina is not a manipulative seductress, she decides she's actually brain-damaged with the mind of a child. That's funny. The heartwarming part is that she immediately resolves to take care of Katarina as she would any other child in need.
• Speaking of children in need, when Maria realizes one of the rescued children has Light magic, she forces the kingdom to agree to support all of them before she will even tell them who it is.
• After Katarina breaks through the "Leave Your Quest" Test of the Duchess Claes' etiquette book, Maria reads the dedication.
  To my daughter, who I am most proud.
  She can do anything, and does.
• Shana calls Maria "Mother". Maria thinks about how she should correct her, since she hasn't been formally adopted... but doesn't. Several times after, she mentally refers to Shana as her daughter, despite denying it aloud.
• Chapter 258: Keith finally meets the rest of the family, and can't help think that they're all exactly like Katarina in the best ways.
  And then it turned out there were two more carriages worth of relatives to meet, all of them treating him like family as a matter of course. And as his mother pulled him forward and introduced him as "My wonderful son Keith," as if she had completely forgotten the fact she hadn't borne him, as he was surrounded by people who smiled the same welcoming, accepting smile of the first person who had ever shown him kindness, Keith Claes once more thanked his luck that the twists and turns of life had led him to meet Katarina Claes.
