Clearly you haven't been keeping up. This carnival forces everyone who enters to face their own fears. Only those who have truly accepted their fears are the only ones who can make it through unscathed. Are you so certain you wish to run head first into that?
They are not useless. We don't even know how many people are trapped in there along with Allana. And considering Mr. Dark has the power to turn her into an eight year old, we need to approach with caution.
I am more than willing to go in there and get here, but we cannot go in ready to attack everything. I am ready to face my fears. Are you prepared to face yours?
