Okay so... to explain a little, Lucy and Natsu made a bet about whether or not Gray liked Juvia. Lucy kissed him in front of Juvia so that there would be a misunderstanding and Gary would have to explain. She really liked them as a couple and did it to help get them together, she's not a whore. Lucy said told you so because it was a bet and Natsu kissed her because it was his way of confessing, that was why he wasn't all that upset about losing the bet-it gave him a perfect moment. And Lyon... well... That part should be self-explanitory. There. I explained it. JUST. FOR. YOU.
