Jax has to work hard to keep a straight face at the sign of the not-half-elf pulling out so many random odds and ends. He nearly outright laughs at the helmet he is handed. Had it been a joke, he would not have found it funny. It is the earnest sincerity that amuses him so much. As a result, Jax responds more nicely than he would have to other people trying the same action. He offers the helmet back while saying, "It's appreciated, really. But I use magic, and pieces of armor like this interfere too much to cast spells. Why don't you give it to someone else who can make more use of it? I'm sure it'd be better off that way."
