Hmmm. Sabriel was actually kind of intimidated by Javert at first- accidentally baptising a complete stranger was part of it- and then that sense of intimidation gave way to exasperation and a certain amount of guilt. (And up until he showed up on her post she wasn't sure if he was somehow involved in Amon's attack or not.)

Now she's still kind of exasperated, but also respectful! And she's glad he's also concerned about Malicant, and there's also a teeny tiny bit of a protectiveness she feels towards all her students.
