While I expect Lacroix to reference souls in that scene, he does not -- at least, not in the version enshrined on the DVD.

You're kidding! O_O I must never have watched this one properly on DVD, then, because I'm sure I would have noticed such an omission:

LC: I should play again, but I'll never compare to them. Why do you suppose that is, Nicholas? Is it because they have a soul?

N: And you do not.

LC: We do not.

It's one of those bits that are absolutely crystalline in my head, down to the way Nigel shapes and stresses the word "soul." I can't remember exactly what he says after that, at least in part because Nick isn't paying attention, because he's busy noticing that the girl is missing. But he's referring back a few lines, to the banter as they entered the tavern, when Nick says something to the effect of "music feeds the soul."

I did not notice Janette looking at Lacroix in that scene at all. I will have to watch for it.

Reviewing my memory, I have a hunch that it's a glance offscreen, and that I read the direction as being toward LaCroix just out of frame. It could actually be at Sarah. I've never questioned the perception.

It wouldn't be the first time I filled in past the edges of the frame without realizing it. In this same scene, in fact -- when I went to recreate Janette's costume for amilyn (I had forgotten, that's the reason I watched the particular scene so many times), I was amazed to discover we never saw all of it. I had a complete image in my head, apparently constructed from a cocktail of my knowledge of the period silhouette and the foley sound of her skirts rustling, that doesn't exist on screen. Not a single clear shot that extends below her knee level.
