I guess I'd have to see the pattern to know just where you mean, but I think I can sort of picture it. Just do whatever looks good! For gaps, I often will pick up a stitch in the gap area, or even two stitches if it's a big span, and knit it together with the adjacent stitch on the next round (don't forget!).
Hope that helps!
