Your code is fine. You just never set the reusable identifier of the cell so they are not reused (as you noticed).

In you custom cell class, implement the method reuseIdentifier:

- (NSString *) reuseIdentifier {
    return @"NarrativeCell";
}

or set the identifier in interface builder (in the inspector for the cell).
