-45 minutes later-

'I refuse to do it Sherlock' Lyanna cried from behind the bathroom door.

'Lyanna, we are going to be late' replied Sherlock.

Sherlock had spent the last 30 minutes trying to get Lyanna to leave the bathroom, so he could see what she looked like in her dress.

'I do not care Sherlock' replied Lyanna 'I am not going and that is final'

'Lyanna' Sherlock said firmly 'You have 5 minutes to leave that bathroom of your own accord. If you do not leave, then I shall get you out – with or without your permission'

'That is never going to happen Sherlock' came Lyanna's reply.

-5 minutes later-

'I cannot believe you broke the door down' cried Lyanna, as Sherlock hailed a cab.

Sherlock just looked at her.

'Yes, you are right' replied Lyanna 'I can believe it – this is you we are talking about'

Sherlock smirked in triumph, as he opened the door of the taxi for Lyanna.

'Thank you' said Lyanna, as Sherlock shut the door behind him.

'You are going to have to take that coat off at the restaurant Lyanna' said Sherlock 'Therefore, I will eventually see that dress'

'I am working on a way around that situation' replied Lyanna – pulling her military coat tighter around her.

'Hmmm' replied Sherlock

The taxi ride was quiet – a comfortable silence for both the occupants of the taxi.

'The Swan, here we are' said the cabbie.

Sherlock went to pay, however Lyanna beat him to it.

Sherlock just scowled as he clamoured out of the taxi, and waited for Lyanna to catch up.

The pair entered the restaurant.

'Good evening' said the waiter 'How can I help?'

'Reservation for two' said Lyanna

'What's the name please?' inquired the waiter

'Holmes' replied Lyanna.

Sherlock smiled.

'Ah yes' said the waiter 'Table 5, please follow me'

The waiter walked off, with Lyanna and Sherlock following behind.

'May I take your coats?' inquired the waiter

Sherlock slipped his coat off and handed it to the waiter. The waiter then turned to Lyanna. Sherlock smirked while Lyanna hesitated. She then decided to give up and she slipped her coat off. Sherlock smirk disappeared as his eyes scanned over Lyanna. She looked lovely – the white dress highlighted her black curls and complimented her grey eyes.

'Shut up' said Lyanna as she sat down at the table

'I did not say anything' replied Sherlock, as he proceeded to take his seat.

'You were thinking – it's annoying' replied Lyanna with smile

'Yes, well –' began Sherlock.

'Sherlock, look' interrupted Lyanna

'What?' inquired Sherlock

'Behind you' whispered Lyanna

Sherlock turned himself slightly and looked behind. There he saw John sat at the table behind. He watched as John pulled out a small velvet box from his pocket, opened it, smiled; and then placed it back in his pocket.

'We came here to see John get engaged?' inquired Sherlock

'Surprise' replied Lyanna

'You were right' said Sherlock

'About what?' inquired Lyanna

'This is definitely going to be good Saturday night entertainment' replied Sherlock

Lyanna laughed.

-10 minutes later-

After 10 minutes of failed conversation between Sherlock and Lyanna. Lyanna spotted someone and she smiled.

'What is it?' inquired Sherlock

'Mary has just arrived' replied Lyanna

Lyanna and Sherlock watched as John greeted Mary with a kiss, before the couple ordered their drinks.

'Have you decided what you shall be eating tonight?' inquired the waiter

Sherlock ordered for himself and for Lyanna- as Lyanna was too preoccupied with keeping an eye on Mary and John.

-20 minutes later-

Lyanna's and Sherlock's food arrived and Lyanna decided that now was the best time to attempt a conversation with Sherlock Holmes.

'Will you miss him?' inquired Lyanna

'Miss who?' inquired Sherlock as he cut into his meal

'John' replied Lyanna

Sherlock ignored the question, and instead he ate a mouthful of food.

'Sherlock, you cannot just avoid the question' said Lyanna

'I am not avoiding the question' replied Sherlock 'I am simply ignoring it'

Lyanna just rolled her eyes before tucking into her meal.

The pair ate their dinner in silence – which suited them both just fine.

Once they had finished, the waiter came and cleared up their plates.

'Oh my-' said Lyanna

'Is he-?' began Sherlock

Lyanna nodded.

Sherlock turned around to see John Watson bending down on one knee. Lyanna and Sherlock watched as John spoke to Mary before producing the velvet box from his pocket. The pair then saw Mary nod and John jumped up and hugged her close. Lyanna smiled as John pushed the ring onto Mary's finger. Lyanna then had an idea.

'Waiter' she called

'Yes madam?' inquired the waiter

'Could you do me a favour?' inquired Lyanna

'Of course' replied the waiter

Lyanna motioned for the waiter to come closer, and she whispered in his ear. Sherlock gave Lyanna a confused look, as the waiter nodded and left the table.

'Watch' said Lyanna, as she motioned over to John and Mary's table.

-At table 6 (John and Mary)-

'Here we are' said the waiter, as he brought over a bottle of champagne.

'Oh John' Mary cried

'Um, we didn't order that' said John

'Ah, it is compliments of another customer in the restaurant. They wished to congratulate you' replied waiter

'Excuse me' said John 'But could you tell me which table that bottle of champagne came from?'

'Of course sir' said the waiter 'Table 5, over there'

John looked over at table 5 and saw two very familiar heads of black curly hair.

'Excuse me Mary' said John 'I will b right back'

-At table 5 (Sherlock and Lyanna)-

'Oh God' said Lyanna

'What?' inquired Sherlock

'John is headed this way – and he looks angry' replied Lyanna 'Menus up?'

'Absolutely' replied Sherlock, as both he and Lyanna hid behind their menus.

However, their menus were soon ripped out of their hands by a very angry John Watson.

'Oh hi John' said Sherlock

'Fancy seeing you here' said Lyanna

'What the hell are you two doing here?' yelled John

'Well, would you look at the time' said Lyanna 'We really should be getting back to Baker Street – wouldn't you agree Sherlock?'

'Oh yes' replied Sherlock 'Time to go'

And with that, the pair grabbed thier coats and took off before John could interrogate them.

'Now you understand why I paid the bill when I did' Sherlock said, once he and Lyanna were both back at Baker Street

'Indeed' replied Lyanna 'Well done'

'Thank you' replied Sherlock

'No' said Lyanna 'Thank you, this evening has been lovely'

'You're welcome' replied Sherlock 'And thank you for being such good company'

'My pleasure' replied Lyanna

'Lyanna, it is rather late, so you are welcome to spend the night' said Sherlock 'John's room is empty, so you may sleep there'

'Thank you' replied Lyanna, as she pulled out her phone.

'Staying at Baker Street tonight – LH'

'I already know. Do not forget your training Monday morning – MH'

'I wouldn't miss it for the world – LH'

'Goodnight Lyanna – MH'

'Goodnight Uncle Mycroft – LH'

'Tea?' Lyanna asked Sherlock

'Thank you' replied Sherlock, as he picked up his violin

Lyanna nodded and headed out to the kitchen. She made Sherlock's tea, while listening to the soothing music of his violin.
