"Tell me again, Caster... what is your specialty as a mage? If you are a healer, there are many injured soldiers who require aid and succor coming in by the droves. Your work there is never done unless the momentary raids are at a pause. If you're strong in offense, then the front line is in need of your strength while Merlin squanders about. If defense is your talent, then the walls against the demonic front is needed."

You have a brain, do you not? I am not going to instruct every single order to you like a dog when you are capable of thinking and making decisions yourself. Unless being treated like a mongrel is some sort of pleasure for you? Don't disappoint me by saying yes."
