@ Sane *The same thing he did when he saved her from Gajeel* I did include that -_- and yeah its interferring like rescuing, help etc. including all those examples you made. *Or are you guys saying that Natsu was right in refusing help from Twin Dragons of Sabertooth because they were 'interfering'?* Oh no we're not saying that at all, (like believe me, I was annoyed when he was refusing) we just trying to let you understand that Natsu has been interfering in Lucy's fights no matter what the situation is. And also, you said Lucy been interferring in Natsu fights but not the other way round, you never said what they were. I mean all I know is she interferred his fight with F. Rogue which wasn't really intentional nor of her own will if she wanted to or not like Natsu been doing considering she was thrown all the way there. And there's Tenrou Island where Kain had her roll down hill to where Natsu was fighting Ultear but then also he interfered by preventing Kain from attacking her so...I wouldn't count that I guess. :/

Most of their fights involves POF or bs power ups or lets not forget my favorite one, "because she's Erza" though. >_>
