I love "In late, out early" : that last sentence is so much more powerful like that.
The trouble is that I don't have a next chapter to read right now! What does he say???
Nice piece, as always. I have a few comments though:
* "I get paid either way" : that one felt out of place here. I don't know if it's just because of the positioning or if I don't feel like that character would think that, but it felt wrong somehow. Sorry I can't be more specific.
* "and tanned skin brightened in a smile" : this felt clumsy and strange, since skin can obviously not change its color with someone's moods (unless it's part of the magic system. If so, you need to explain more).
* "make the stars look like glowing spheres" : the astronomer jumped on his chair here. A galilean telescope would bring out a magnification of 30 at best. At that magnification, stars should still be pinpoints.
* "Si, I am feeling sorry for myself..." : Mathieu's reaction in this whole passage seems strange. Despair, then dismissal, then anger. It feels like he doesn't know which emotion to choose, which makes the reader jump from one emotion to the next.
* "Si, I would love nothing more than to bash ..." : that sentence doesn't seem to follow what came before. Mathieu was addressing Sasha, not Mena, so why did she say that?
* "Her father pays more for her..." : I never took Mathieu to be of the jaleous type before, so this feels a little out of place.
Nothing terribly wrong here, as you can see : some parts would benefit from a little bit of clarification, but it's otherwise pretty good.
I hope he says the right thing, I'm in a mood for a nice duel scene!
