Just to make it clear (possibly reiterate, I'm uncertain whether I've specified this before), none of you should ever feel forced to make "filler" posts just to post something or just because no one else seems to have anything to post. I want your characters (and by extension, you) to drive the plot of the RP (this is their story, after all, whereas I am merely the narrator), but I also realize that all of your characters are currently somewhat lost and unaware of what's going on and probably a bit reliant on Victor for the time being, even though there has been some distrust towards him already.
If ever there is a time when none of you feel like your character has anything worthwhile to add to the situation, just say so and I will have my NPCs do something instead; in this case Victor, despite his newfound interest in keeping your characters compliant, is still primarily concerned with getting Adelicia to safety and wants to get moving; if none of your characters seem to have anything else keeping him there he is going to want to leave.
For that same reason I also highly prefer that you decline posting rather than just keep silent, so that if everyone declines I know to take action as the GM; I only drive the plot when you don't know where to take it.
EDIT: That isn't to say that you're not allowed to make "filler" posts, by the way, just that you aren't expected to do so unless you want to.
