How did this happen?

Crime scene

'Doctor isles' Tony said I smiled I missed his voice so much.I'm glad I kept my head down he hasn't saw me yet.
Frankie waved me over, oh how I loved this man. 'Maura, hey the body is down there' he said pointing to where the NCIS team was. 'Okay,thanks Frankie' I smiled, no one knew we were dating apart from Frost. I slowly walked down to the body and began to examine it hoping Gibbs wouldn't recognise me.
"Okay, she's ready to go to the morgue, I'll see you there." I said to John.

*Janes POV*
Maura was just walking up to meet me at the top of the hill when we both heard "Maura babe wait" and another voice saying "Kate wait up" one sounded like my brother and the other sounded like that Tony guy from NCIS. Why were they both calling her? Why was Frankie calling her 'babe'? I thought to myself. We both turned around and walked to Tony.
*Frankies POV*
I called Maura babe at work damnit! Now she's walking over to that Tony guy that called her Kate, who is this guy? I walked over to Frost while they were talking to him.
*Mauras POV*
"Kate? Who's Kate? You must be thinking of someone else" I said to Tony. "No I know it's you Kate I could recognise that smile anywhere. Can we talk?" He asked, "fine I guess we can. One condition you can't call me Kate. It's doctor Isles or Maura" I said. "Okay Maura"

*in the car with Tony*
"Why Kate? Why would you do that to us? You left me heartbroken! Was it something I done?"
"No Tony it wasn't, I didn't want you dying, I left a letter with director Vance but I'm guessing he never gave it to you" I said while concentrating on driving.
"No he didn't, Kate what about all the family talk we had? We planned on a future together now you live here with some other family" "Tony I don't think you understand. I needed to fake it I didn't want you to die. I loved you believe me but I needed to get out of there I was a danger to everyone." I said just as I was pulling into BPD.
"Loved? You don't love me anymore?You know I went on loads of dates with other girls even the new girl Ziva and I still couldn't get over you" he said as he leaned in and kissed me. Out of habit I kissed back. Tony pulled away first. "Really Kate you still don't love me?"
I was about to say something until I heard my car door open. It was Frankie.

*Frankies POV*
"Maura- What the hell?!" I screamed. I could hear Maura or Kate or whatever her name was calling after me. "Frankie wait!" Was all I heard before closing the doors. I didn't want anything to do with her after that. I went into Jane and told her the whole story, turns out she already knew. I thought Maura or Kate whatever loved me? Not that Tony guy! Who even is he?, Frankie wondered to himself. "I guess I'll find out later" "find out what later" Ma said "nothing Ma, I gotta go now" I said kissing her on the cheek.
