Honestly, this is probably Camelot's most fatal flaw. She attempts to take on far too many responsibilities at once and ends up stretching herself too thin whenever a new unexpected one pops up (as demonstrated in her first IC fight). This is the double-edged sword to her desire to help as many people as possible. She's going to have to get used to truly relying on the strength of other people for a change.
As far as Lumiere... paranoia towards one of the Grand Ministry's most prolific agents is such a [i]wonderful[/i] thing.
