'Is it me or is Dr Coulter hanging around a lot more than before?' Elliot thought out loud as he and Ollie walked around the ward, catching Seb out of the corner of their eyes as he attempted to speak to Mo about a patient. It had been about a week since he returned, and he had turned up on Darwin at least once a day on the premise of seeing a patient, always at the 'request' of another doctor of course.
'Oh yes, haven't you heard? All cardiothoracic patients obviously have psychiatric issues that need Dr Coulter, and Dr Coulter only' Ollie sighed sarcastically and Elliot let out a laugh. 'Honestly, I can't work out if he's more like a bad penny or a bad smell'
'Well...are things ok with you and Zosia?'
'Yes, everything's perfect' Ollie smiled. 'I think she's getting a bit fed up with Seb just turning up on the ward but I'm confident that he'll get the picture eventually' he smirked. The pair watched Seb as he finished speaking to Mo- they saw him look around, peer into rooms through the windows and when he could see Zosia wasn't there, he would leave, and it was repeatedly so that this would happen and he wouldn't appear back until the next shift change.
'Well, if there are any problems, let me know' Elliot offered and Ollie smiled. 'Did you say Zosia's coming in at 10?'
'Yes, she's going to her mother's grave with her father...it would have been her birthday. I offered to go with them, but she thought it would be best to be just her and Guy for this morning, so I'm going later on with her. It's a hard day for her'
'Of course, I understand' Elliot smiled.

Seb's eyes lit up as he saw Zosia scurry onto the ward, and he pretended not to stare. 'Nice necklace' Seb called out as she hurried past. She was late for the agreed time to start her shift, and she turned around flustered. 'Thank you, it was- oh shit I'm so late!' She panicked as she caught with sight of the clock. As she hurried into the locker room, Seb's face went from the smile he was holding out for Zosia, to that of someone who had just sucked on a sour lemon. 'Oh what was that Zosia? It was a present from lover boy?' He thought to himself, bitterly. 'Of course it was.' No matter how much he tried to calm and rationalise his thoughts, he was jealous. Jealous, bitter and angry.

When he was sure Zosia had left the locker room and had thrown herself with into diagnosing and treating her patients (a quality that Seb nevertheless truly admired), he looked around and managed to sneak into the locker room undetected. He knew which locker belonged to Zosia, so he quickly unlocked the door and there it was, the necklace. It was gold with a bumblebee pendant. Just looking at it filled him with rage, and as he swiped it and shives it into his pocket, he slammed the door again, and quickly made his way out of the locker room, and wandered back up the corridor like nothing had happened.
Several hours later, Zosia was desperate to catch a couple of moments to herself. She went into her locker to grab some money to get a coffee from Pulses but before she slammed the door shut, a terrible feeling overcame her as she realised her necklace was missing. The one that belonged to her beloved mother. She had been wearing it a lot recently, and it meant more to her than ever today, on the anniversary of her mama's birthday, and she started to panic. She quickly lifted up her bag, various paperwork, and other things littering her locker, but it definitely wasn't there. Her eyes started to well up with tears and then Ollie came in.
'Hey? Hey what's the matter?' Ollie asked gently as he approached Zosia, holding his arms out. He out his arms around her but he could tell she was panicking about something.
'Mama's necklace, it's gone' she gasped, tears starting to fall down her cheeks. Ollie kissed her on the cheek.
'Hey it's ok, it can't have gone far, did you definitely leave it in your locker?'
'Yes, yes, I took it off when I got on shift and put it here, at the front, but now it's gone' she worried, and Ollie started to look around.
'Ok don't worry, it'll turn up around here somewhere. Are you sure, 100% sure, it was here?'
'Yes!' Zosia snapped. 'Sorry, it's just, obviously it's really important to me' she calmed down and Ollie took her into his arms. He kissed her on the forehead and she hugged him.
'It'll turn up' he reassured.

Meanwhile, in Seb's office, he opened a drawer and tossed the necklace into it. 'Valentine will go mad that she lost such a beautiful necklace' he thought to himself, vindictively. He knew what he would do with the necklace. The truth was, throughout his 'sabbatical' he had formulated a plan to win Zosia back, and he had spent 6 long months planning his return to the hospital. Valentine would eventually reject her, and then he would swoop in and save the day. He turned around to his wall, covered in photos of Zosia and pieces of clothing that she had left at his before she went to New York and cheated on him. He pinned up the necklace for safe keeping. He was going to win her back, back, and she was either going to put up a fight or come quietly...he just needed to get her alone.

At the end of their shift, Zosia and Ollie walked hand in hand out of the hospital, and drove the cemetery where her mother, Anya, was buried. She had always promised herself that she would spend as much time as possible with Anya on her birthday, and she was glad to have Ollie's company. When they reached it, Ollie set down some flowers that he had bought to put down, which Zosia thought was really thoughtful of him. She looked down and welled up.
'I'm so sorry mama, I've lost your necklace' she wept and Ollie placed two calming and comforting hands on her shoulders, and kissed her on the cheek from behind. 'Typical of today, really' she laughed. 'Do you remember, it must have been your 30th, I was only little, but I grabbed your handbag to play with by the lake we visited with dad, and I dropped it in by mistake?' She laughed and Ollie let out a little chuckle, he was moved by the way Zosia was talking to her. 'Anyway, I will find it, so don't worry' she reassured. 'Happy birthday mama' Zosia welled up, and Ollie put his arms around her. 'It feels so unnatural talking to a grave, but I know she's up there somewhere listening to me. She's probably calling me a clumsy girl for losing the necklace' she laughed.
'I'm sure it'll turn up Zosh' he smiled to reassure her.
'Thank you Ollie...it means a lot that you came' she smiled.
'It's ok, I know how hard these things can be. They never get easier' he said, sadly, thinking about Penny's and Tara's birthdays he had spent at their gravesides. They both knew how the other one felt in these situations, and it was this mutual understanding that was one of the things that made them stronger every day. 'I love you Zosia' he smiled, and she looked up at him, still in his arms.
'I love you too' she replied, as he kissed her gently. They held each other as they thought about those they had lost, and although they were cold, Ollie didn't want to force Zosia to leave until she was ready. They spent about an hour chatting on the bench next to Anya's grave, talking about Anya, Penny and Tara. Zosia understood a lot more about Ollie every time he talked about them, and was sad that she would never get to meet them, and Ollie felt the same about Zosia whenever she talked about Anya. They had opened up a lot about each other, and at times they felt vulnerable yet safe at the same time. It really was something beautiful that they had, and they both felt optimistic that nothing would ruin it.
