Jane and Casey sat crossed legged on the picnic rug eating in silence. Casey had turned up at the office about half an hour earlier with a bunch of flowers and a basket telling Jane he had something very special planned. It had been a long morning of looking through cold cases so Jane had been happy to oblige and even a little excited by Casey's spontaneity. Yet now they were sat in awkward silence as Jane tried to determine what was wrong with Casey. He had been fidgeting non-stop since they had arrived at the park and had only really spoken to offer Jane more food or wine. Jane had initially tried to fill the awkward silence babbling about work and Maura and Tommy Junior but had eventually admitted defeat and was now sat quietly picking at a tub of grapes.

"Jane?" The sudden break in silence made her jump but she looked up smiling at Casey hoping he was finally starting a proper conversation. "I know I've not always been around…"

"Not this again Casey" interrupted Jane "honestly I don't mind I know how much your job means to you and I know you had it pretty tough with the…"

"shhhh Jane". Jane was a little indignant at being told to be quiet but let Casey continue. "What I was going to say is that even though I've not been around I'm here now. My priorities have changed and you are far more important to me than any job. On that final tour I realised how much I miss you when I'm away and well, I don't want to be without you ever again." Casey shifted position until he was on one knee and a smile crept up at the corners of Jane's mouth as she watched him pull out a small velvet box. "What I'm trying to say is… will you marry me?" Jane was grinning now as she flung her arms around his neck.

"Yes!" she tilted her face up towards him and kissed him. As his strong arms wrapped around her waist pulling her in tighter. She pulled away. "Oh my god, I've got to tell Maura!" She jumped up and was running back in the direction of the office before Casey could even respond.

Maura hadn't been at the office but Korsak had told her she had finished early and would probably be at home. When Jane got to Maura's house however she wasn't there. Jane let herself in and was sat on the sofa still bouncing slightly with excitement when Maura returned. Jane jumped up immediately throwing her hands in the air "I'm engaged!" A flicker of something Jane couldn't quite place flashed across Maura's face before it was replaced with a large smile. Jane grabbed her friend and hugged her, lifting her of her feet making her giggle as she swung the smaller woman around.

"Let's see it then" Maura said when Jane finally placed her down.

Jane's brow creased in confusion, "what?"

"The ring silly" Maura replied as she took Jane's left hand in her own.

"Shit" Jane mumbled as the two women looked down at Jane's bare finger. She had left in such a rush she had forgotten to put the ring on. At that moment Jane's phone buzzed to life and Casey's name appeared on the screen. Jane hurriedly pulled her hand out of Maura's grip and opened the phone.

"Hi" she said walking away from Maura.

"You told Maura yet?"

"Yeh, she said congratulations" Jane replied smiling oblivious to the edge in Casey's voice. After the phone call had finished Jane hugged Maura once more and kissed her on the cheek before hurrying back to see Casey.

Jane entered the apartment to find Casey sprawled on the Couch with a beer in his hand. He watched as she dropped her keys in the bowl and walked towards him, but his expression did not soften as it usually did when he saw her. "You are unbelievable you know that?" He spat, this time it was impossible for Jane not to notice the edge in his voice.

"I'm sorry about the ring" she mumbled looking at the floor. "Trust me to do something as stupid as that", she laughed in a futile attempt to lighten the mood.

"I proposed, and you ran off. Without the ring. To Maura!" His voice was dangerously low as he stood up to face Jane properly.

"Come on now that's not fair, Maura's my best friend." Jane was angry now too, yes she had been stupid but she didn't deserve this sort of treatment.

"She's not just that though is she? I should be the only person you're thinking of at that moment. You kissed me and thought of her! You forgot the fucking ring!" Casey was shouting now and had got closer to Jane with every sentence. Their faces were now centimetres from each other. Jane squirmed away as he continued his tirade, shouting about how she never had any time for him, how he had tried to ignore it but he just couldn't any more.

"Look just give me the ring, it's beautiful really. I want to marry you, I said yes." Jane pleaded.

"It's too late Jane! You've made it quite clear you don't want it." He shook his head turning away in disgust.

"Casey! What the hell is wrong with you?"

"What the hell is wrong with me? You love your best friend far more than me, she's all you could think about on what should be one of the most special days of our lives." Casey seemed resigned now "and you know what I'm jealous, really jealous because I know I could never compete with her." With that he left the apartment slamming the door behind him.

Jane sank down on to the sofa holding her head in her hands as she tried to process what had just happened.
