Chapter Two

Eliza...

"So are saying that Tom is engaged to your best friend? That really odd, kind of bitchy skank, awkward who all night tried to get the guys attention at my hen night? That lovely girl?" Mary asks Molly in disbelief. "That awkward girl to Tom, next week?" she repeats it trying to make sense of any it. She tries to blow her tea cool and starts to drink it then looks at Molly with amusement, "Remember my hen night, Molly?" Mary teases she tries to hide her smile from behind her tea cup.

Molly frowns at Mary. Mary knew that Molly did not remember anything that night (she just heard stories, apparently according to Mary they are hilarious stories-including starting to auction off men who didn't think they'd get dated, tone deaf karaoke, and glee talks especially over playing that one Journey song). She remembers the before, the middle of it was a blur and the end well it was pretty much draws a blank. When she would try to remember it her head would hurt to a point that she had to stop trying to recall what happened. She knows what to blame to this little amnesia incent—tequila. Marie forced her (or convinced really…) to take shots of this evil liquor to numb her pain away and of course screaming that men are a scum of the earth.

But the real reason of her resulting to the comfort of alcohol that night was Sherlock.

Molly had a long day at the morgue that night, when she got home Tom surprised her with a romantic dinner having known that she had a very bad day. Her night was starting to get better until she got a phone call from Sherlock (who kept calling her until she would answer) demanding that she gets back to St. Barts because he refused to work with the other pathologist and kept calling them incompetent.

She still remembers everything from that night clearly…

"It is my night off Sherlock, I haven't had a proper night off in weeks. Dr. Donahue is more than capable of helping you with whatever you need her to do." She gave Tom an apologetic look when she finally answered after seven continues calls from Sherlock and a miss call from Charlotte begging her to deal with him.

"I cannot work with her. She doesn't understand what I want. I hate repeating myself twice." He says stubbornly.

She rolls her eyes, "Can and will not is different thing, I will not always be there. Work with whatever you can have. And while you are at it stop harassing my colleague." She tries to reprimands him but it sounded like she was bored and not caring about what he just said.

"Then she needs to start acting like she has the brains that supposedly helped her through med school or she probably shagged her way through to pass." He insults. She could tell that he is rolling his eyes.

"Sherlock…" She hissed at him. She pinches the bridge of her nose trying to breathe calming herself or she'd start an unnecessary fight with him.

"Doesn't matter, Lestrade said I can have the best to work with me. I refuse anyone of them to work with me and none of them is as brilliant as you."

She sighs, knowing fairly well that she is about to cave to his demands and also she doesn't really have the mood or the strength to argue with him anymore. he always wins and makes too good of a point to even try but when she looks at Tom she found the strength to stand up for herself. The disappointment look on his face as he starts wrapping up the dinner he just made, he seems to know that no matter what relationship status he has with molly he always believes that Sherlock comes first.

She takes a deep breath summoning that strength from her fiancé's face. Sherlock isn't wining this, if its starts a row then so be it. "No Sherlock. Tonight is my night off and I am not on call. Use whatever resources you have there. You have a good night because I certainly am going to have one with my fiancé." She hangs up on him and smiling at Tom whose eyes shinned like its Christmas morning. He started to open a bottle of wine and pouring it on the glasses, he looked so happy.

So she tried her best to hide the fact that she was shaking on the inside. She just snapped at Sherlock there is surely a horrible consequence at this act of defiance. Oh, put yourself together woman. You are allowed to live your life without needing to please him all the time. You have Tom, sweet, attentive, loving, honest, and right for you Tom. She tells herself but not before she gulps the whole glass of wine in front of her.

"Slow down sailor," Tom winks at her. He serves her a spoon full of his homemade lasagna. He kisses her forehead before he takes the seat beside her.

They were about to eat their dinner when Sherlock burst through the door followed by John who gives Molly apologetic look. Sherlock on the other hand looks very angry and he makes a bee line towards Molly who stands up and meet his angry gaze. "Sherlock," she says firmly she crosses her arms across her chest to keep her arms from shaking.

"You are trespassing." Tom stands in between Sherlock and Molly.

Sherlock just ignores Tom. He keeps his intense gaze on her, giving her a dark dangerous smile "Did you just hang up on me and stood up for yourself, Molly?" he says darkly. "I would applaud you on an average day. But I suggest you play house on a different day not when two girls are still missing and that body at Barts is the only link to finding them."

"I ain't saying it again, mate." Tom warned.

"Sherlock," John says tentatively by the door. He looks ready just in case Tom does something rash, like making aiming for Sherlock's face or throat. He is contemplating if he is going to stop Tom or laugh at Sherlock.

Sherlock just ignores everyone else in the room but her. He doesn't even acknowledge that Tom is talking to him let alone standing in front of him who is standing really close as well. He just merely leans close, towering over Molly. They are just glowering at each other, if only could kill.

"You two better decide quickly, as Sherlock said there are two girls whose life is in danger here," John states quietly and patiently after a few moments of tension shared between Sherlock, Molly and Tom. He could have stopped Sherlock from barging in Molly's flat but he is way too stubborn and no matter what you say to him he tries to defy it.

"Then I think they should leave." Tom says as he turns to Molly when he hears her sigh. He gives her a desperate look hoping she would do what he has asked. He sees her expression softening and he understands what that means. He is winning.

She touches her fiancé's arm oh how she wishes that touch would be of comfort to him because she knows that her decision is going to hurt him. But as much as she hates the fact that Sherlock is most of the time correct, and the fact that he is on the case can only mean one thing; Lestrade is desperate to find these girls. With a sigh of defeat and mumbles, "Give me five minutes."

"Molly!" Tom moans in despair.

Sherlock looked pleased, he smiled that he secretly won the lottery and not wanting to tell anyone. "Good. There is a cab waiting for you, John and I will go on ahead." He claps his hand together and walks away. "Come on John! The game is on!"

John just nods at Molly, "See you at Barts. Sorry about this Tom." he says and started following Sherlock. They could hear them arguing.

"Tom," she starts when he starts to clean up the dining table. She reaches for him but he moves away from her, so she clenches her fist and hugs herself, "This is work Tom, I just can't—"

"Every time!" He bellows and drops the plate on the table heavily causing the plates to make a loud crash. She flinches, when he notices this he says it quietly again which stung in her heart more than him saying it angrily, "Every time Molly…"

"Tom, please…"

"Just go Molly. He needs you." He picks up the food and throws it on the trash. "You know what, I'm going to go. I am exhausted waiting up for you to come home every time he summons for you." He grabs his coat and reaches for his scarf, he stares at the dark gray scarf and throws it on the ground. "Do remember Molly that I proposed to you. I love you Molly but I hope you can see he is using you. I just don't want to see you hurt." He leaves slamming the door shut behind him.

She just helped Sherlock quietly and just did what ever he asked without making small talk because she was too annoyed at him, which suited him just fine and it irritated Molly more. But in all honesty it made her sadder than angrier really. She didn't understand why she couldn't say no to him, her fiancé should be first not second in line after Sherlock. She needs to keep her feelings in check... She isnt in love with him(she thinks) she loves Tom. She just wants this night to get it over with, so she can probably crawl into a hole after she either drinks her emotions away or finish a pint of ice cream she isn't sure yet.

When she finally finished what ever Sherlock needed and all he did was say thank you and then left her alone in the lab going to Lestrade with the answers to find the missing girls. She was about to head home when she got a call from Marie who just broke up with her boyfriend and begged her to go out.

"I need you Mollykins... I havent seen you since your engagement party... I need to search the answers of my pain in the end of the bottle. And you got to find it with me... Please Molly Violet Hooper."

As soon as Molly agreed to go with Marie, John found her before she could call for a taxi. He was apologizing for how Sherlock was acting, "I tried to stop him, but..." He shakes his head thinking he is only making the situation worse. "Any-road, Mary wants to talk to you..." He hands her his mobile.

"Molly!" Mary screams on the other end, she could barely hear her due to the loud noises in the background it sounded like shes at a club or a bar, "It's my hen night! You should come!"

She looks at John who smiles at her. He probably told his future bride what Sherlock did to her night and probably thinks a company of other people would do her good, "It is alright my friend Marie asked me to go out tonight. We don't want to impose."

"Well of course not! Bring her too! The more the merrier! Its just my bridal party with me, I know they do not mind, right ladies?" Then Molly could hear a loud whooping noise in the background which she assumes are from Mary's friends. "Come meet us at the Fabric!" Then Mary hangs up not before making a whoo noise herself.

Molly hands the mobile back to John, "Well you girls have fun." He says as he looks at his watch and then calls someone on the phone and from the insane mumbling plus John's eyes rolling she knew he is talking to Sherlock, "Alright I am on my way, calm down..." He waves goodbye to Molly and starts walking away. "Give me five minutes, and no Sherlock you can't stay on the phone with me just to prove a point..."

So after many shots of tequila and swearing off men(mostly Sherlock), she woke up that morning with the after effects of a terrible hang-over and having no recollection of the night before. She was laying on her own bed wearing only her knickers. Tom waiting on her hand and food all morning while she tries to wake her alcohol-induced comatose best friend on her couch who was only on her undergarments (which she is alright with since Marie has the tendency to strip off her clothes especially if there is a man around).

The only person she found out of the norm was Tom. Sure he was always attentive but that morning he was too everything like he did something bad as if the fight was his fault even though they both knew it was hers. Or probably because she was sick all morning so she was just guessing she was overthinking... After that day Tom didn't do much of a fuss if Sherlock needed help with his cases after her normal working hours and actually Tom was even more nicer and sweeter which was one of the big reasons why she broke her engagement with him because she felt that she did not deserve him at all...

Eliza, Mary and John's little girl, cooing in Molly's arms brought her back to the present. She just put her lips lightly on the sleeping baby's forehead trying to a hide a giggle from the cuteness the baby is giving off, "You and John just make the most beautiful child ever, don't tell my godchild I'm more biased to your little one." She says quietly.

Mary just grinned brightly at her, "I know! I am thinking I want a couple more of these..." She says a little too loudly so John could hear who was in the kitchen making more tea.

"Dont you think that is something you and I talk about in private?" John calls teasingly from the kitchen.

"Possibly," Mary responds and she winks at Molly who was trying her best not to giggle so she wouldn't wake Eliza.

Molly started humming a tune her dad used to sing to her when she was younger when she notices Eliza slowly stirring awake and the little one made the most adorable noise that when Molly looked up at Mary, she got a frown from the new mother, "What?" she asks

"Only you can make her do that adorable sound. Every time you sing to her. It makes me jealous..."

Molly laughs heartily causing the little one to wake but the she did not cry she was just eyeing her as if remembering that they had spent a month together by themselves as a pretend mother and daughter. Well, Molly certainly remembered. When Moriarty threatened England Sherlock thought it was best to hide everyone he cares for so he wouldn't have any distractions to take down the criminal consultant but John wouldn't leave his side and so does Mary though Molly would have gladly stayed behind to help out but it proved more danger for Molly than anyone else because she was the reason Sherlock was able to stay dead due to the fake the autopsy report. So after much talking into, She and Eliza hid in South Africa until the Moriarty issue was dealt with and it was about a month until the two got to return back to England.

"Oh and Sherlock." Mary added as she took another sip of her tea.

Molly perked up at from trying to hum Eliza back to sleep. She ignored Mary's knowing look and asks, "What about Sherlock?"

"You and him are the only ones who bring out the extra ordinary shine in her. Sure she is adorable and I love her to little tiny pieces but she gets more adorable when you and Sherlock are with her."

"Really?" Molly inquires with a smile, she knows Sherlock visits the Watsons but she has never seen him interact with Eliza.

"Oh yeah, he comes over here when he is stumped with a case and just takes Eliza and talks to her about his dilemma. I wouldn't be surprised if the my daughter's first words would be 'Murder'..." Mary says amusingly.

"If that happens I'd have a nice decent talk with Sherlock and hopefully not punch him in the throat. We already have enough sociopaths in this family, I want her to be normal, at least." John says as he sits beside Mary. The girls laughed at John's frown, he shook his head ignoring their amusement so he changes the topic, "So when is this wedding?"

"Exactly a week from today, the Swan-Turner nuptials is on the way! We just got done looking at bridesmaid dresses... Thank god she just told me to pick out what ever i want to wear since it is such short notice to order the dresses. She wanted Salmon Pink!"

"Thank heavens for that." Mary says sarcastically, teasing her. "If you have a problem going stag at the wedding I can help you find a bloke to go with."

Molly shakes her head, "Thanks though... But Sherlock going with me."

As if it was rehearsed, Mary and John who was drinking their tea at the same time, spat their sip and started choking, "Sherlock?!" both said in unison shock shows on their face.

"That bastard who left my wedding early is going to this wedding... voluntarily?" John says in disbelief.

Molly shrugged, she kept asking this herself but she just stopped trying to figure out what Sherlock thinks half the time, "As a favor, he seemed alright with it."

Mary just giggled and leans towards John whispering something, "... Quids then." Was the only thing she could hear.

"Sorry?" Molly asks as she glowers at Mary who just shrugged innocently while John just finished his tea in one gulp avoiding her gaze.

"I'm getting another cuppa," John stands up but not before he and Mary shared a knowing look as if smiling at their own little inside joke.

Molly was about to ask what was going on when Sherlock burst through the doors. "Hello Watsons," he says briefly. He pauses when he sees Molly he smiles at her then walks to her and takes Eliza from her easily as if he is used to snatching the sleeping baby from someone who is cuddling with them.

"Oi!" Molly protested, crossing her arms on her chest stubbornly and pouted at Mary.

Mary just laughed, "Don't look at me, he takes her from me every time as if I wasn't the one who carried her for 9 months and suffer a 20 hour labor of hell." she rolls her eyes, "Want a cuppa?" She asks and heads to the kitchen.

Molly was just looking at Sherlock interact with Eliza who is now wide awake and smiling as if understanding every word he is saying. Molly swears she heard the little one chuckle too but she's positive Sherlock didn't hear any of it because he is is rambling away about his current case. She smiled realizing that she seemed to be enjoying herself watching him than holding Eliza herself. Who would have thought that he would look good or normal carrying her as if she was his own child if she wasn't such a split image of John other than her bright blonde hair and Mary's eyes she is a little clone of her father (a little joke saying that John is a pretty girl).

She caught a glimpse of Mary eyeing her. She frowns at Mary when she winked at her then did a funny gesture at Sherlock. She looks away from either away and she could tell she's blushing. Oh Molly... Just try to not act all stupid around him. Way to have someone catch you drooling over him. She mentally to slap her forehead.

"Oh Molly, let me know what color you'd be planning on wearing at Meat Dagger's wedding and the rehearsal." Sherlock says looking away from the smiling baby and gazing deep into her eyes making her blush more.

"Rehearsal?" Molly repeats. "What rehearsal?"

Sherlock sits beside her and he starts rock Eliza as she started to make a fuss, looking like she is uncomfortable. Molly playfully tickles Eliza's feet and making baby noises, she stopped when he sighs and rolls his eyes at her, "Well if I am to go with you with at Meat-" Molly gives him the disapproving look for not calling her ex-fiancé his correct name "This wedding it'll be more credible that I am your date than a last minute choice if I go with you to both events..." He tells her as if it was something of a common knowledge.

Her eyes meet together in confusion, "You really don't need to go with me to the rehearsal, just the wedding. And why do you need to know what I am wearing?" She sputtered lightly.

He just smirked at her, "Nonsense. I told you I'd to go with you, so that includes both events we aren't going half-assed now. And so asking what you're planning to wear so I could at least match what you're wearing, most women worry about that correct?" He didn't wait for her response and stands up again going to the kitchen to speak to John about their new case.

What do most women worry about, as she recalled from her conversation with him last week she is not really like most women. So what did he mean by that? She only asked for the wedding... Why is he being super nice?

She was too preoccupied with her thoughts that she didn't even notice Mary sitting next to her until she cleared her throat to get her attention, "So you and Sherlock at the wedding and the rehearsal..." Mary teased.

Molly laughed, "Shut up, Mary."

Mary just bites her lip to stop herself from giggling again, "He did say date... And you know weddings tend to be romantic and there's dancing too..."

"Stop it..." Molly couldn't help but smile, "This is Sherlock we are talking about, he is just repaying a favor nothing else."

"Okay then whatever you say," Mary says in a singing voice and winks at her and handed her a warm cuppa.

Molly just rolls her eyes and shakes her head ignoring Mary. Of course Sherlock may have mentioned that he owes her a dance too... But she doesn't really need to mention it or even hold Sherlock to that. And it is just a friend accompanying someone to an ex's wedding (hopefully to get a spiteful reaction from Tom).

She sneaks a look at him while pretended to drink her tea, he looked towards her direction and he gave her a genuine smile that made her heart leap in her chest then he continues to talk to John. She bites her lips trying to stop herself from a giggle trying to bubble up her lips... Its just a friend accompanying someone to a wedding right? She shouldn't get her hopes up... But its doesn't really hurt anyone if she just imagine she'd get a dance from Sherlock though.
