Sabine's masters?

What could this mean? Sorry, I don't really have any ideas, just wanted to bring up this coincidence. Hope that is a satisfactory first post.

The idea has been around for some time, the most serious consequences this could have would be that the fiends know about Snarl, and now that V accepted their deal, they might want to use V to obtain its power for themselves (or against the forces of good, at least).

Quite likely, though no one knows for sure. Its fit with her "personal" errands

[Delgarde]

Quite likely indeed. It also plays rather nicely with the fact that Hayley has yet to work out whether Sabine is demon or devil - if her masters are separately LE, NE and CE, Sabine's alignment seems almost as questionable as V's gender.
