Lorna lay on the floor behind her desk, an empty sick bay meant Lorna Heiland was messing. She'd already healed her eye herself having managed to fling a huge dollop of shampoo in it before coming to work. Now she was stretching out her limbs, she considered it Yoga but not having ever done Yoga she actually didn't know whether or not it was? She could take a nap? No, she wasn't tired. McCoy had made her eat dinner before her shift as well so she wasn't hungry. Standing up she looked around the bay, clicking her fingers to get her brain working she wondered how she could fill her time. Narrowing her eyes, an idea came to mind and she grinned in self-regard and glee.

"Computer, rotate lighting…" Lorna stopped talking.

"Order not recognised," The computerised voice replied.

"Computer, delay order." There was something wrong? She had an overwhelming feeling of Deja vu. She couldn't put her finger on it but something wasn't right. Sitting behind her desk she tapped her fingers along the edge until she'd thoroughly exhausted every probable reason for her feeling like something was peculiar. Deciding she was hungry she went to the replicator but couldn't decide between cake or hummus.

"Oh Pie?!" Now there was an idea. "No, not pie." She admonished herself. "Don't be ridiculous!" Shaking her head at herself she carried on with her duties, taking inventory, making sure the crew physicals were all planned in. She'd put her earbuds in at some point and was currently listening to some classical music which was very calming and nice. She flittered around, puffing up pillows and restocking shelves.

At around the halfway mark of her shift she got an interesting case of an allergic reaction from one of the Botanists, that kept her quite busy…

"Were you in here yesterday?" she asked Elaine Grundy.

"No?" Elaine answered looking slightly perplexed.

"You sure? You didn't have an allergic reaction yesterday?" Lorna asked.

"I'm sure Doctor Heiland, are you sure you're not getting me mixed up with somebody else?" The Botanist asked and Lorna laughed, dismissing the notion.

"Must be, sorry, all the days seem the blending into one at the moment." Lorna finished up what she was doing and when Elaine Grundy had left typed up her notes on her PADD. That's when she saw the date. She'd been putting down the wrong date all day yesterday?!

Lorna continued with her day like any other, not long after Crewman Xia came in with quite a nasty plasma burn.

"Everything alright Doc?" he asked, she'd been staring at him since the moment he'd walked in?!

"Everything's fine, why would you ask?" Lorna answered a little abruptly.

"No reason!" Xia nervously countered. Lorna looked at him suspiciously and then dropped her equipment on the bed.

"Weren't you in here yesterday?" she asked suspiciously.

"No?"

"I think you were?" her face was disconcertingly close to his.

"I wasn't."

"Have you hit your head recently Crewman?" Lorna stood back with her arms crossed, she suspected memory loss but from what she wasn't sure. Placing her hands on the man's head she started feeling for bumps.

"I haven't hit my head Doctor," he told her, now altogether freaked out.

"Fine," she said letting her arms fall by her sides. "Have it your way," Lorna finished up treating his burns and sent him on his way.

She kept quiet when Ensign Gale came in with a bump to her head but when Commander Chlapoutakis came in with a sore tummy Lorna held her hands up in front of him.

"No! No way!" The Commander looked on in bewildered shock.

"I'm sorry?" he started but Lorna shushed him, gave him a hypospray quickly (she'd prepped it, knowing but secretly hoping he wouldn't come in) and ushered him out. Pulling her chair round she sat directly in front of the door.

Waiting.

"I'm not crazy," she whispered to herself.

(There was that sound again, from behind the panel.) There was no way she was getting into all that again!

Lorna watched as the bay door swished open to reveal Kostas and as soon as she saw the Doctor stood before her she manically laughed and briskly walked past them. Kostas didn't think anything of it.

After all, this was Lorna Heiland we are talking about.

"Dinners on the table, make sure you eat!" Lorna heard McCoy shout from the living room as she dried her hair, blearily looking around for her uniform she squinted her eye closed. For the third time that week she'd managed to get shampoo in her eye.

"Wait a minute?" Lorna whispered to herself.

"Everything alright Darlin'?" Turning she looked at McCoy who was stood watching her from the doorframe, plastering on a smile she told him everything was fine and quickly finished getting dressed. Scoffing her dinner Lorna fled their quarters and hurriedly walked down the corridor to the turbolift.

She needed to make sure.

Lorna did nothing until Elaine Grundy walked through the door. As she treated the Botanist she brought her lips to the woman's ear.

"I know what your doing," she whispered threateningly but when Elaine looked at her in horror Lorna knew she had no idea what she was talking about.

Sitting at her desk she reviewed the medical logs, creasing her brow in confusion when they only went up to three days ago.

"Unless," she started. "We haven't got that far?" Opening a comm channel to Kostas she got the other Doctor to the med bay early so that she go find out what the hell was going on.

"It'll be quiet anyway," they started.

"Something tells me you'll get an allergic reaction, plasma burn, knock to the head and a pretty bad case of gastroenteritis." Kostas laughed, obviously not knowing why Lorna's prediction was so specific. Lorna said nothing and left.

"Captain!" Lorna shouted as she slipped through the opening door of the turbolift and stepped out onto the bridge, missing the step she nearly went flying but righted herself at the last minute. As if nothing had happened she stopped in front of Kirk and got straight to the point.

"We have a problem."

"Problem?"

"Yeah, problem. We're stuck, stuck on stardate four one one five three point seven." Kirk didn't blink.

"That's today Doctor Heiland," he told her laughing lightly.

"I know that Captain," Lorna was losing her patience.

"We haven't got to the end of today yet, how could we be stuck?" He decided to go with it, in the back of his mind he wondered if McCoy had set her up to play a trick on him.

"Because I've already done today three times Captain," she told him in all seriousness.

"Captain, we're approaching the planet." Lorna looked at Sulu who had just spoken.

"Thank you Mister Sulu, put us in orbit." Kirk turned to Spock. "Mister Spock?" Spock turned and inclined his head.

"Captain, the planet is experiencing strong solar activity, it will take me some time to gather my readings."

"Proceed Mister Spock," Kirk turned back to Lorna. "Sorry Doc, what were you saying?" Lorna rolled her eyes and huffed.

"Never mind," she mumbled as she left the bridge. She was obviously going to have to work this one out on her own.

"What are you doing?" McCoy sat still as Lorna carried out a myriad of medical checks on him. He had asked why but when she had failed to answer him he'd just gone with the flow. He found it easier that way sometimes.

"Any feelings of Déjà vu?" she asked, looking at the readings on her tricorder.

"No," he answered slowly.

"Umhum, my turn." She told him.

"Your turn what?" he asked as he jumped off the bed.

"I want you to do a full physical Leonard, full psych evaluation as well." She told him firmly.

"Darlin' when I imagined us playing Doctors together I didn't imagine this," McCoy said laughing, trying to lighten the mood.

"This is no time for your tomfoolery Leonard, let's get on with it please." McCoy was taken aback by her tone and demeanour. Lorna was never serious, except when it came to food. Or the very real danger of creepy children that looked like old people! It was thing apparently.

"Alright Darlin', you wanna tell me what I'm looking for?" he asked.

"Anything," Lorna answered, laying back on the bed and hoping to god there was something wrong with her because if there wasn't, then, what the hell was she going to do next?

"Elaine Grundy doesn't know, neither does Crewman Xia or Commander Chlapoutakis." Lorna lay on the floor behind her desk, she'd already healed her eye (again) having managed to fling a huge dollop of shampoo in it before coming to work (again). Now she was stretching out her limbs, still feeling full from the dinner McCoy had made her eat. "That doesn't mean there might not be somebody else on board who's aware of what's going on as well." Scrambling to her feet Lorna ran from the bay and towards the mess hall. Grundy wouldn't appear for another hour anyway. It was one of the main meal times on the ship and the majority of the crew would be in there having breakfast, or dinner, or whatever meal it was for them. Standing with a sea of people around her Lorna wondered how best to get everybody's attention.

Climbing onto a chair and then the table Lorna grabbed a plate and with all of her strength threw it on the ground.

"Well, that worked." She said to herself as a sea of faces all turned to her expectantly. She opened her mouth to ask if anybody was reliving the same day like her but didn't know how to phrase the question. "Please can you come speak to me if you have done this before, I mean I've done this before. If I've done this before please see me." When she saw the sea of faces turn confused she rolled her eyes. "Does anybody feel like they're doing the same thing over and over?" she shouted out. When a timid hand came up Lorna yelped and pointed at the nervous Lieutenant. "How many times have you gone through today?" she asked. The Lieutenant immediately looked sheepish and as if he wished he'd never put his hand up.

"Well, I mean, I've been working at the same station for three years now and at my last performance review I did say I wanted to maybe, have a change? A secondment… or something?" Lorna's heart sank.

"Right, well, thanks for that." Getting down from the table she stalked out the mess hall now knowing she was the only one who knew they were all repeating stardate four one one five three point seven over and over again.

Lorna skipped the shower, there was no way she was going through the pain of shampoo in her eye again! Legging it out of their quarters (she waited for McCoy to go to bed, she didn't want all the questions and it felt awful to hide anything from McCoy but she just didn't have the time!). Lorna headed straight to the Bridge, this time though she wasn't going to waste her time with Thicky McThicky, she was going straight to the Vulcan!

"Commander Spock!" she shouted from the turbolift, earning a look from the entire bridge crew. From Spock, she earned a signature eyebrow raise.

"Doctor Heiland, is everything alright?" he asked.

"Yeah yeah, well, no, kind of, I need your help." She told him.

"Very well but I am due to carry out research on a nearby planet and…"

"Don't worry about that Commander," she interrupted. "It'll be experiencing strong solar activity anyway, you've got time." Spock's interest was piqued.

"How do you know that Doctor Heiland?" he asked.

"Because," she leant in closer. "We've already been here."

"We have not explored this region of space before Doctor…" Spock started but Lorna shaking her head and laughing stopped him from finishing his sentence.

"Oh we have Commander, about eight times now. On this day, at this time, only I'm the only one who knows it." Spock didn't even miss a beat before replying.

"You are purporting we are in a loop of some kind?" Lorna nodded her head slowly.

"A time loop yes, only we repeat one day. One day Commander." Holding her finger up to labour her point Lorna hoped to God he would take her seriously. It was looking hopeful.

"I'm telling you I'm not crazy!" Lorna huffed as she sat in the med bay surrounded by McCoy, Kirk and Spock. It had taken all of five minutes after her conversation with Spock to have arrived there being subjected to every test under the sun. "Goddamnit!"

This was going to be harder than she thought.

"If you are indeed repeating the same day over and over again Doc," said Kirk. "Then what's stopping you from doing anything you wanted?" he asked. Trust him to think of that!

And that's when the lightbulb went off over Lorna's head. Grinning she looked at the three men.

"Absolutely. Nothing."

She broke her leg skateboarding in the corridor the first loop. Typical.

She stayed in bed all day on the second.

On the third?

"Captain!" shouted Chekov, turning in his chair and gawking at Kirk in horror.

"What is it?"

"Doctor Heiland Captain, she's stolen a shuttlecraft Sir and broken through the forcefield?!" (She'd also stole a load of booze from the mess but who's counting!)

"Hey Doc, how are you?" Kirk greeted Lorna as he walked by her in the corridor. He never even saw the right hook coming, Lorna was surprised at how much blood there was. Like seriously, it sprayed up the wall and everything! She figured it was his fault for her being in this situation anyway!

Loop fifteen she played the day out, having lost interest in doing things with no consequences. The fact was it was lonely, she wanted to see McCoy, not on this day but the next. She wanted to carry on with her life. Finishing her shift she went back to their quarters where all she wanted to do was be close to her Husband.

"You're especially cuddly today," McCoy commented, laughing at the way Lorna had attached herself to his side. Lorna just hummed, keeping her eyes closed and trying to forget that soon enough she'd be back on the floor of the med bay in no time at all. "I was thinking we could try and cook that new dish tomorrow, you know, the one you found in that old cookbook? What do you say?" Looking up at his face Lorna smiled sadly.

"That's sound nice," she answered, knowing it would never happen.

She needed to fix this.

"Spock! You, me, now!" Lorna grabbed the arm of the Vulcan and pulled him towards the briefing room, she had no time to waste. Well, that wasn't true was it but you know what I mean?!

At the sixtieth loop mark Lorna screamed. I mean ear piercing scream at the top of her lungs.

She'd found herself righting everything that went wrong that day before it happened. Saving Elaine Grundy from her allergic reaction. Stopping Crewman Xia's plasma burn. She didn't always prevent Commander Chlapoutakis' gastroenteritis though, he kind of deserved it.

She could never quite stop herself from splashing shampoo in her eye though.

She started each one of her conversations with Spock explaining to him all of their previous conversations, sometimes it worked, sometimes she'd find herself back in the med bay. But as each 'day' passed they debunked one of the ever expanding number of potential causes they came up with.

"You need to be present for the entire day on the Bridge Doctor Heiland, to see what occurs around the time of our orbiting the planet." Spock told her on her sixty seventh loop.

"You think there's something on the planet?" she asked, a glimmer of hope.

"I do not know Doctor, that's what you will find out." On the next loop Lorna reiterated everything that happened to Spock.

"The planet was experiencing strong solar activity, there was a geomagnetic disturbance and you said that when it hit its peak it somehow connected with the Enterprise?" Lorna had no idea what she was saying?

"And what were you doing Doctor?" Spock asked.

"I was here, on the Bridge, you told me to stay and watch what happened?"

"No Doctor, what were you doing the first time?" Spock asked and that's when Lorna smiled.

"I was messing with things I shouldn't have been Commander!" she answered grinning. "I think you've done it Spock!" she shouted excited.

"You neglect to realise Doctor that I have done nothing, if what you say is true. I will forget everything we have discovered today and you will have to explain it again." Spock nearly felt sympathy for the woman.

"Oh don't give up that easily Spock," Lorna said. "You never know, you might not throw me in the brig the next loop!"

Lorna let the next day play out as it should have again, did have? Whatever, she was tired. She went through the entire day as if she never had before. When she was sat at her desk and staring at the panel, her heart was in her throat when she heard the banging sound.

"It's showtime," she whispered to herself. If Spock was right, if her touching the relay at the exact same time as the geomagnetic disturbance was the cause of the loop then perhaps doing it again would cancel the whole thing out? Holding the screwdriver Lorna took deep breaths. "Please work please work please work." Her hand was shaking uncontrollably as she brought the tool to the relay.

The jolt shot her clear across the floor, leaving her splayed out, down for the count and sizzling. A few minutes later she came to; "Ow?" Turning onto her side Lorna took a moment to ascertain her injuries but was interrupted by Kostas walking through the main door.

"Oh hey!" she wondered if it had worked. "Funny story… " she carried on. "I think something's in there?"

"Something? Could you be more specific?" Kostas asked as they pulled her up off the floor and led her towards one of the beds.

"I feel like my fingers are full of energy," Lorna stared at her hands as Kostas just waved a tricorder in front of her.

"You know you're going to get in trouble for this don't you…?" Kostas started but was distracted by the sound of knocking coming from the panel, Lorna tried to play along.

"I told you!" Lorna exclaimed. Kostas looked from the panel to Lorna and then back again.

"You have got to be kidding me," the Doctor exclaimed, shaking their head. "Let's find out whether or not you've done any lasting damage."

"Fingers crossed," Lorna answered, laughing fearfully.

Lorna lay on the floor behind her desk and cried, bawled, wept and howled. It hadn't worked.

All Lorna wanted to do was spend time with McCoy, the problem was as far as he was concerned he'd just been on a day shift and was tired and she was due to go on a night shift. She would suggest them doing something, anything but he'd always laugh and tell her to stop messing around, get to work. One loop she lost it with him and they had a huge row. That was the worst loop.

The next twenty loops she learnt how to play guitar and one of McCoy's favourite songs. She'd surprise him with it one day.

She read every medical journal.

She ran through the corridors naked.

Sat in the Captain's chair and refused to get out.

Stopped Crewman Barker from dumping his Girlfriend (she was the best thing that ever happened to him).

Cured a disease.

Shaved her head.

"Perhaps we are to not visit the planet at all?" Spock hypothesised. Lorna was pinching the bridge of her nose with her fingers, her eyes were closed and she was sat on the floor, legs crossed and back slouched.

"What?" she replied a little too unkindly. Spock took in her countenance and creased his brow.

"Doctor, may I ask? How many times have you experienced a… loop?" Lorna looked up at him and smiled miserably.

"This will be my one hundred and fifty ninth Commander," she said. "How do I prevent the Enterprise from visiting the planet Spock? We're already heading towards it when I start a new loop."

"Then you must divert us somehow."

"I have to try to explain to you why we can't visit the planet and then you're going to just accept that and convince the Captain we change course?" Lorna looked at him as if he was a moron.

"No Doctor, you must do it yourself." Lorna stared at him incredulously.

She was going to commit mutiny!

"I'm going to steal the Enterprise?" she asked.

"Affirmative Doctor." Lorna barked with laughter.

"Well, that'll be interesting." Then a thought popped in her head. "So me messing with that panel and getting electrocuted? That doesn't have any relevance to what's happening?" she asked.

"No Doctor, that was simply illogical." Spock said as he arched a 'judgey' eyebrow her way.

"Great, thanks."

Lorna wrote a note to McCoy, it explained everything. She knew it wouldn't be long before the loop started again and he'd forget everything she'd done (that was if she wasn't successful) but still, she hated the idea of him not knowing why she'd seemingly tried to steal the Enterprise for no reason and feeling hurt and betrayed by her, not even for a moment. She gave him the biggest kiss before she left for her shift.

"What was that for?" he asked bemused, holding her in his arms lovingly.

"For being you," she answered.

"I'm no more me than usual," Lorna smiled at him.

"No, but you being you is always enough for me. It will always be enough for me." McCoy's faced straightened, something was wrong. Before he could ask Lorna flashed him a smile and left quickly.

She had very little time, if she was going to do this she had to act fast and follow Spock's instructions to the letter.

First thing first, she had to get her hands on a phaser rifle. The armoury was too heavily secured so her only option was to acquire one from another source. That's where the next phase came into play. Jogging to the transporter room she took a deep breath before walking in.

"Oh, hey Doctor Heiland." Crewman Bijal greeted her.

"Hey, how are you?" her voice sounded strained and weird.

"I'm good thanks, what are you doing here?"

"Well, funny you should ask. I was checking crew medicals and it turns out you missed your mud flea vaccine." Lorna shrugged her shoulders comically.

"My what?" the man asked.

"Not to worry though," she said ignoring his question. "I've got it with me, won't take a sec." Holding the hypospray up in front of her she closed the gap between them.

"Oh? Okay?" Lorna brought the hypospray full of sedative up to his neck.

"Sorry," she whispered and in a moment of terror Crewman Bijal heard her, knew it wasn't a vaccine and flung up his arms. It was too late though, sleeping like a baby on the floor Lorna helped herself to a phaser rifle and readied herself for the next stage of the plan.

It would have been the most, epic, coolest thing in the world for Lorna to walk down a corridor holding a phaser rifle in her hand if it wasn't for the fact that she was on her way to the Bridge where she was about to stun everybody and take over the ship. Still, she bet she looked pretty boss!

There was only one person who walked passed her and if they were surprised to see a medical doctor wielding a weapon they certainly didn't say anything. The turbolift ride was full of inspirational pep talk.

"You can do this! Just get it done! Doesn't matter if it doesn't work! You've got this! Just stun everybody and turn the ship around, easy. Remember, stun people, turn ship around." Lorna checked the rifle was on the stun setting. "That'd be awkward!" she laughed. She felt the lift come to a stop and readied herself for the door opening.

And then it did.

Lorna Heiland stunned everybody in record time (taking a couple of loops to practice her aim had been well worth it).

"So far so good." Lorna ran over to the helm and sat down, quickly tapping away and entering the new coordinates (a few more loops learning how to steer a ship had been good use of her time also). Just as she was about to confirm her order the lift door swished open and Lorna's heart sank when she saw McCoy's face.

"Lorna?!" he exclaimed. "What in the hell are you doing?!" Lorna looked down at the station beside her and the view screen showing the planet coming into view. She had run out of time.

"I can't explain Leonard! You're just going to have to trust me." She pleaded.

"Trust you!" McCoy shouted at her. "Darlin' you're committing mutiny! I read your note but..."

"I'm doing it for a very good reason!" she told him. "Please Leonard, let me do this." McCoy growled in frustration and ran his hands over his face.

"Damnit Lorna you might be sick!" Lorna sighed, he wasn't sure. She could see that he was torn, his loyalty to his Wife struggling with his loyalty to the crew. She loved him for it.

"Leonard?" she shouted, gaining his attention.

"What Lorna?" McCoy looked at her aghast.

"Would you rather…" She turned to face him, her hand going behind her back and hovering over the console. She spotted the phaser in his hand when he'd walked in. She honestly didn't know whether he'd use it on her.

"This is no time for one of your damned questions Darlin'." McCoy's finger hovered over the trigger.

"No, I suppose it isn't." In a flurry of movement Lorna slammed her hand down on the console as she fired the phaser at her Husband who simultaneously fired his phaser at his Wife. The pair fell to ground, both unconscious and neither knowing what would happen next.

Lorna dried her hair in the bathroom whilst taking in her appearance. Apart from the bags under her eyes she wasn't too displeased. Walking out to the bedroom Lorna saw McCoy hovering around the door.

"You just here for the show?" she asked teasingly.

"Perhaps," he answered smirking at her.

"Don't worry, I'll make sure I have some dinner before my shift." She told him as she pulled a uniform from the wardrobe.

"You forgot didn't you?" Lorna looked at him confused. "I told you this morning that I'd taken you off night shift, we're going to be working together for the next work pattern." Lorna dropped her uniform on the floor. Her jaw fell open and she couldn't move. "What?" McCoy asked, not knowing why she was reacting the way she was.

"What stardate is it?" she whispered.

"What? Lorna, what are you talking about?" McCoy had no idea what was going on.

"Stardate Leonard!" running form the bedroom she picked up her PADD off the table in the lounge and stared at the date.

"You mind telling me what the hell you're doing Darlin'?" McCoy's voice asked from behind her.

"It's tomorrow," she said turning to him, her eyes brimming with tears of joy. "It worked."

"Lorna, you know I think you're mad a box of frogs on any day of the week but now you're scaring me." McCoy came to stand in front of her, taking her hand he squeezed it tightly. "Is everything alright?" he asked. Laughing and crying at the same time Lorna nodded her head and then she remembered.

"You shot me!" she told him.

"What? When?" He was this close to doing a full psych exam on her.

"Never mind, it's today and that's all that matters. Interesting about the amnesia though?" She shrugged her shoulders, she was Doctor not a Physicist! "I love you," she told him before walking back to the bedroom.

"Love you too Darlin'," McCoy replied, staring at her in wonderment.

On Leonard H. McCoy's Birthday a few months later he had the most wondrous, bizarre and utterly amazing experience of having his Wife sing and play his favourite song for him. As he stood and watched in awe Kirk came to stand by him.

"I didn't know she was such a great guitarist Bones," he commented.

"Neither did I," McCoy replied stunned. "Neither did I."

The fact that her cooking had improved, she could ride a skateboard like a pro now and was one of the best marksman on the ship didn't go unnoticed either. They went unexplained but they didn't go unnoticed. But why would anybody ever be surprised at anything Lorna Heiland did? She was Lorna Heiland after all!
