Rinoa's inability to buy a useful weapon for Irvine is amusing. The pathetic group of resistance fighters that Rinoa has gathered also seems par for the course, given that both members of her other team seemed to be rather unusual. Irvine's sarcastic thoughts on the matter are very funny.
Your Irvine is more the professional than I am accustomed to seeing in fanfiction. I enjoy the balance in his character between flippancy and shrewdness.
