Can anyone tell me how to show only the subcategory of a post? I can use the_category to get me both the category and its child, of course. But I can't find a way to show only the child. (I'm doing this because the page on which the posts appear is a category page, so the parent is obvious.)
I have searched through the codex and the support forum but haven't found anything quite on point.
Any help would be greatly appreciated.
