Since Ollie had first seen Tyler, a week had passed. To him it seemed like a year- a year filled with surgery sessions he either didn't understand or didn't know why they were being performed, discharging seemingly healthy patients he could have sworn were screaming twenty minutes beforehand and hopeless attempts to get Tyler to yell at him. All of them had ended in him, angry and red-faced, watching her calmly walk off to chase up something he hadn't asked her to. It was a living hell and all of the other doctors didn't understand him. If they'd had a chance to work with the golden girl, they would have grabbed it with both hands.

Tyler was enjoying herself. For the first time in her life, she wasn't the odd one out. On th CT ward, she was surrounded by equally bright and interesting people that she could properly talk to. She knew that she was an unusual F1, but that didn't stop her getting as involved as she could. The Head CT Surgeon had also taken an interest in her and Tyler was looking forward to sitting her exams much sooner than any other junior. She was working hard- often doubling up her shifts to gain experience and hang around to observe theatre procedures. Her sleep was suffering, but that was nothing caffeine and sugar couldn't solve.

In fact, the only thing that she was not happy with, was her boss, Mr Valentine. When she showed off to the other doctors, they appreciated it, and praised her. Mr Valentine, on the other hand, just seemed to become infuriated. The end of every fay was characterised by him picking fault at her and she was nearing breaking point. Tyler had considered discussing Valentine's behaviour with Hanssen, but she soon realised that winding him up was as good a punishment as any- and it was just so easy.

Someone was shaking Tyler's shoulder. She scrunched her face up against the light that seemed to be pouring onto her face. Had she not shut the curtains? Someone shook her shoulder again and she sat up abruptly. She wasn't at home after all. The CT staffroom came unforgivingly into sharp focus. She wiped a hand over her face and looked to her left. A senior nurse she hadn't seen before was stood beside her. He had dark brown hair swept off his face and was staring at her.

'I'm sorry, sir,' Tyler muttered, and got up, glancing at her watch.

'Nah, you're alright, don't worry,' said the nurse. 'I'm Fletch, by the way.' He shook her hand. She realised, with a bit of embarrassment hers was still clammy from sleep.

'Tyler,' she replied.

'Now, I know who you are.' Fletch nudged her. 'You're only the talk of the whole hospital.'

Tyler hid a grin and looked at the time again. She'd only been asleep three hours. There was still another hour before her shift started and she needed at least another half-hour's kip. She sat back down again and, noticing Fletch had gone to the counter to make a coffee, shut her eyes again.

'Oi, don't go back to sleep again,' he said. 'Took me an age to wake you up the first time.'

'I still got an hour before my shift starts,' Tyler muttered, shuffling into a more comfortable position.

'Sorry, not today. You're working on AAU with us. Mr Valentine not say? I've got to give you a tour, show you the ropes and that. Lucky you came in early, really.'

Tyler saw no reason to tell Fletch that she'd never gone home.

AAU was chaos compared to the general serenity of the CT ward. Patients were being ferried in rapidly from the ED and sent away just as quickly. Patients shuffled around like zombies, trailing machines and drip stands. One of these was quickly intercepted by Fletch, who quickly pushed him back towards his bed.

'Shouldn't be up yet, Mr Huntingdon. Wait till Dr Copeland gives you the all-clear. Dom!' he called down the ward to the Nurses' Station where an unassuming man in burgundy scrubs looked up. 'Mr Huntingdon's wandering again!' The man nodded and hurried down the ward. Tyler was shown beds, cupboards, corridors, lifts, alarms, offices and the staffroom. For any other F1, she was sure, this would be overwhelming, but she felt the familiar buzz of adrenaline begin to run in her veins. This was what she was made for!

'So, Fletch, what d'you want me to do?'
