If he adds NaLi scene after this, that would imply a imagination-driven love-triangle(because it can't really be called a real love triangle) and if he is serious then this series would automatically fall into the romance category, which won't happen. There maybe romance, but it doesn't "deal" with romances. And Lisanna has already accepted Lucy as being better with Natsu albeit no hint of love or anything.
