I'm sure there is no (and never will be a) love triangle between Lucy, Natsu and Lisanna. So far Lisanna has shown more interest in coupling Lucy and Natsu together than in taking Natsu for herself.

Even in the past she was only teasing Natsu, without having any real interest in a romance with him. Yes, they were very good friends to the point where they were almost like actual siblings, but that's all there was.

Everything else is just the product of people seeing romance because they really want to see it, not because it's really there. Sorry if that sounds a bit harsh on the NaLi fans, but as far as I can see it, it's the truth.
