Irvine may be his friend, but he really didn't understand him. Knowing what was going on, why wouldn't he at least try to help?! "No one knows how we're brought here." Not to mention that Zell didn't arrive in a normal way. "It's been years and no one knows how to get back either. There might have been some people who tried. But almost everyone knows the Calamity's a bigger threat! No matter how many people are brought, we need all the help we can get!"
