Abby rushed straight into admit, past Haleh, muttering whether she could cover for her for a few minutes, and hurried into the lounge. It was, thankfully, empty and she sank onto the sofa, pulling out the paper Luka had given her. She unfolded it and read.

To Everyone,

I'm leaving on Friday. I know this may come as a surprise to some of you, but I just don't want a big deal made of it all.

The past four years have been an amazing part of my life, and I have learnt and experienced so much from living and working here.

I've seen you at your worst (John at 3am) and your best, and it's been a privilege working with and getting to know you all.

I wish you all the best in your futures,

Best Wishes

Luka.

Abby read it through twice, glancing over the familiar handwriting. A knock on the door jolted her from her reverie.

'You okay?' Carter asked, walking into the room. Abby nodded and held out the piece of paper.

'It's from Luka.' John frowned and sat next to her, taking the piece of paper. He read through it quickly, Abby watching his expression change as he went.

'Wow.' He said finally, sitting down beside her. 'Where do you?' He held up the letter

'He gave it to me. We've just had coffee and he told me then.' John nodded, then, noticing the tone of her voice.

'Are you alright?' Abby nodded.

'Yeah, it's just a surprise, you know.'

'Yeah.' John muttered. He didn't really know what to say. He looked over at her, and saw a tear running down her face. He extended an arm and put it round her shoulders.

'Why does he have to go?' She whispered.
