You have overridden the line view template, so you don't have to do a new fetch.
If you are trying to create a override template for a folder (since you want to fetch articles), you should override the node/view/full.tpl template in stead.
Another thing: do I have to base the overrides on one type of templates to get the right results? I.E.: Do I have to use a "full template" if I want to show results of that type, or can I just override a "full template" and write my own "line template" as a override?
