Ok I wrote another chapter to get you up to speed. The next chapter will also be a catching up to the present kind of chapter explaining Jenny's death but after that it will all be about Kevin and Tessa (my OC). Please, please, please review and tell me what you think. It's really really important to me.

Chapter 1:

Tessa Harper had never been sure of much in life. Every month she decided that she wanted to major in a new subject, to get her "dream job" in a new career. Her mood was as constant as her fashion sense and she rearranged her room every other week, always growing tired of things that stayed the same for too long.

Despite that, Tessa had grown into herself and by the age of 27 she had a somewhat set path to follow and a constant sense of self. However, there were only 2 things that Tessa ever felt truly sure about and those were that: 1) Tessa was a lesbian and 2) Jenny Duffy-O'Malley was her best friend. They were facts that she had built herself around because they were certain. It was like saying that the sky was blue or the human body had bones inside. They were constant, hard, indisputable truths and nothing anyone said or did could change that.

Or so she thought.

Tessa had met Jenny in high school. Looking back, neither really remembered the exact date or what they'd been doing but somehow, someway they'd become friends. It hadn't been long before Tessa became attracted to the other girl and why shouldn't she have been? Jenny was smart, outrageous and beautiful. Sure, she could be shy and mild mannered at school but in reality Jenny was a party girl and Tessa spent many nights making out with her on the dance floor after they'd both had a little too much to drink.

Tessa knew that Jenny wasn't attracted to her and really, she didn't mind. When Jenny met her first serious boyfriend and stopped going to parties, Tessa had moved on. They never did stop being friends though and soon sloppy club kisses turned into warm hugs and laughing until their sides hurt. Their odd relationship became one of sisterly love and by the time they had graduated they were inseparable, closer than family.

By then Jenny had broken up with her boyfriend and gone back to partying but not as intensely as before. This time she focused on school too and only went home with men, knowing at least that much about herself. Tessa stopped partying all together and for a time she left, taking a year to go travel the world and "find herself". Even so, Jenny was still waiting when she got back and Tessa would never forget the night they had when she'd returned.

She'd been expecting the other girl to suggest they go out dancing or to a bar but instead they'd stayed in and eaten Tessa's favourite take out. They'd watched bad movies and talked until sunrise. By the time morning rolled around they were dancing and singing badly to old pop songs and laughing so hard that tears streamed down their faces. They'd ended the night by making a pact, each promising never to let anything get between them and since then they hadn't, at least not as long as Jenny lived.

At the age of 26 both girls met their long term partners, the people they'd thought were meant for them.

For Tessa that meant Jessica King, a high powered attorney with an impeccable sense of style. They'd met in the café Tessa was working at and after several days of Jessie coming in as a regular, she had asked Tessa out. Tessa had agreed and never looked back. At times she wondered how she had been able to catch the eye of the brown haired beauty. With her mocha coloured skin and lovely dark eyes, Jessie certainly wasn't lacking in the looks department and considering her job, she wasn't short on smarts either. She was interesting, well-read and independent, all the things Tessa liked in a woman. She didn't have time for sweet nothings or stupid jokes but Tessa didn't mind. She liked someone who gave her space but not too much and that someone just happened to be Jessie. Soon that like turned into love and before they knew it they were living together and leading a regular domestic life that would even make Jenny jealous.

For Jenny, meeting her significant other had meant Kevin Ryan. Tessa had met him a couple months after they had gotten together, going on a double date with the couple. She liked Kevin, she really did, but she was wary of him. He was a homicide detective and Tessa was worried that her friend would get hurt. She brushed it off, however, assuming they wouldn't be together for long. Jenny went through boyfriends faster than Tessa went through career ideas and Kevin hadn't exactly seemed like the best fit for her friend in that moment.

They'd surprised her though and she found the detective growing on her. Yes, maybe they were both a little too sweet with each other and yes, maybe they were both a little too dependent on the other but eventually Tessa had found herself liking them together. She'd never seen Jenny like this, so head over heels for someone. When they'd announced their engagement, Tessa had been the first to congratulate them.

She was happy for them and why wouldn't she be? Jenny and Kevin were two of the nicest people she had ever met and although she didn't know him well, she did know that he was funny and kind and really, truly loved her best friend. Anyone with eyes could see it and she wasn't about to stand in the way of their happiness due to one small misgiving she'd had in the beginning.

So she'd accepted maid of honour for the wedding and met all of Kevin's friends and stood next to her best friend as she married the man with the bluest eyes Tessa had ever seen; and honestly? She'd been happy to do it.

How was she supposed to know that those eyes would be her undoing?

Love it? Hate it? PLEASE REVIEW! It would mean so much to me and mean more chapters for you. I'm sure that at least one person out there wants to see Ryan with an OC. If that's you, please tell me what you think. As I've said before, I have absolutely no idea where this plot bunny came from but it just kept jumping around in my head and I couldn't let it go. I'll post a new chapter as soon as possible but I will be much more motivated to if I get some reviews *wink, wink*.

Thanks!
