"I am giving you the command because you can do whatever you want with it," Luke replied. "I know that you won't let the monsters advance too much. Besides, I know that Mom is going to help you and as for the others... I don't trust them with such an important task."
"You should at least say that I won't let the monsters advance at all…" Mark said and then sighed. "Also, you should trust your friends a bit more. Regardless, you can leave it to us."
