Original Commentary

As I said, Sofia doesn't do "nice" very well. Or very often. Has she changed since last we saw her? Kind of. Sofia's desire to be a princess has been mostly edited out of Unlike Minerva, because it didn't have anything to do with the rest of the comic. But it informed her personality. This is what she became when she got closer to the real world, both in terms of the comic's tone and her own exposure to it - Terrence

Modern Commentary
Then again, Brisbane told Robert what the argument was about and that didn't go well for Brisbane. He's afraid that Sofia will mock him also - more than usual. And Brisbane doesn't want to risk going through that again. He has a lot of friends, but he's running low on good friends. - Terrence
