There were arguments about when the first date was.

Riley and Harry and Ginny along with most of the older Weasley-Potter Clan along with two Marauders and their kin, believed it was Kathlynn's first train ride to school. James was overprotective of her on the train, only a tad more so then with his only little brother. And he bought her a ton of chocolate from the Tolley Lady, even though she had her own money.

Severus and much of her family believed it to be when she snuck into Hogsmead a year early, never mind the fact her parents lived in Hogsmead during the school year and had a legitimate reason to be there, to walk around with him. He did buy her lunch at the Hog's Head where Aberforth gave him a discount and free butterbeer.

Many of his cousins believed it was two months into her fourth year after her disasterous break up with Eric Meyers, which he may of caused, but nobody had any proof of that fact. When he led her to the Quittage Pitch and took her for a broom ride because she was still upset. She wasn't upset after that fact, and thus much of the school believed that was the day they started dating.

The fact is it was halfway through her fifth year, they were on his bed in Gryffindor Tower and he was helping her with her OWL homework, when she said that a random sixth year Ravenclaw wanted to ask her out and that she intended to say yes. James got loud and said she had been dating him for a year and a half and that NO she couldn't date anyone else! So Kathlynn pursed her lips and said 'Then take me out to Hogsmead this weekend.' and while he nodded she left. It was later that night when he found out she was just goading him into admitting they were dating. Sneaky Slythering Girl.

So that weekend found them right at the Hog's Head in their seat.

"So Kathlynn?" James asked swishing his butterbeer around in it's goblet.

"Yes Jamie?" She asked chewing on her lunch.

"Why me?" he asked suddenly losing all his Gryffindor Courage and becoming afraid of her answer.

"Your James, James. My best friend, who keeps Vincent Goyal from harrasing me, who helps me prank Professor Longbottom. Who's never said a bad word to me, you help me when Im feeling down, and you make me laugh when I'm crying. You don't believe that I'm useless because I can't brew a potion even though both of my parents are Masters of the craft, you don't think I'm crap at dueling or Defense or Transfiguration even though I am. You dont make fun of me for the fact that plants die around me and the fact Professor Longbottom has banned me from touching any of the plants in the Greenhouses. You think it's cute that I'm good with number's and great at reading runes, you think my Charm work is brilliant. So why not you?" Kathlynn blinked over her meal.

James digested that for a few moments before scowling. "You sneaky little Slytherin, how long have you know we were dating?"

She grinned at him her canines slightly longer then usual and her lavender eyes sparkling. "My first year, Eric was just to get you jealous." she then dumped some money on the table and ran out of the diner, James on her heel. Both laughing at the other, until James managed to catch her under a tree and kissed the living daylights out of her.
