"In all honesty have you ever been in an actual mission or job that involves a lot of fighting?" Because Allen figured at least an understanding of how worlds were different might help with some understanding.

"Where I was from we went on missions. We had no healers, no medical supplies. All we had was the weapons we needed which were always on us and ourselves. The reason is mostly because we can't use the medical supplies during fights and healers were most likely going to die the moment a fight would break out because they can't defend themselves and we might not always be able to." Plus with how few exorcists there actually were it would have just made the protecting thing that much harder.

"So it's not about always being able to magically find something because it's needed. Sometimes you do have to use your own head and what you have to figure out a problem."
