Hello! It's EnduranceInHope with a new chapter. This one shot is a companion piece to the previous chapter that ModernDayBard wrote. I hope you all enjoy the dynamic between Jenny, Sherlock, and Michael. It was a fun piece to write.

If you are liking this story please leave us a review to let us know!

As always, we don't own Sherlock or the songs. Jenny is ModernDayBard's OC.

Jenny was dashing around her apartment trying to quickly change into a set of more comfortable clothes than then the ones she wore to rehearsal that day. She had completely forgotten that she was supposed to help Sherlock watch Michael, Mary and John's son, until she had run into the family at the door of 221 Baker Street. She hoped that she hid her surprise well enough. Mary and John deserved to have a night out… without having to worry about their son.

Now in a pair of leggings and a tunic shirt, Jenny grabbed her computer and hurried out the door and up the stairs to 221 B. She had just reached the door and was about to knock when she heard a crash and the sharp cries of a distressed child. The young actress burst in to see a stack of overturned books on the floor, Michael in tears, and Sherlock standing in between looking confused as to whether he should comfort the child or straighten the books. Jenny took that decision out of his hands.

"Sherlock!" The sharp note in her voice redirected his attention to her. "Take care of the books." He nodded as Jenny strode over to the two-year-old on the ground.

"Michael, honey, what's wrong?" The boy let out a string of sounds that Jenny deciphered to mean he wanted his mum and dad. She picked the boy up, settling him on her hip and allowed him to plant his face into her neck.

"I've never seen him get like this." Jenny turned to Sherlock as he spoke up. He finished stacking the books on a high shelf. "He's usually more calm when I watch him."

"Did Mary leave a bag for him?" Sherlock nodded and pointed to where it sat, in John's old chair. Jenny rummaged through it pulling out a container of apple sauce. "Can you get me a spoon from the kitchen? A CLEAN one." The detective rolled his eyes, but hastened to oblige his friend.

While Jenny was helping Michael eat his snack, Sherlock pulled out a few of the toys that Mary had thought to included in the bag. Tonight's selection included a red, wooden car, a small train set, and a teddy bear. Michael got excited upon seeing the toys.

"Well, Michael which one would you like to play with?" Sherlock asked his small charge.

"TRAIN!" came the enthusiastic response. Jenny laughed and allowed the boy to scamper over to the detective. "Play trains, Uncle Sherlock!" Though shocked for a moment, Sherlock eventually responded by situating himself on the floor and Michael allowed himself to be entertained by his trains and his "uncle."

The hours passed swiftly. Jenny was allowed to join in on the fun and was even able to get out of Michael what he wanted for Christmas (Sherlock practically beamed when the answer was "chemstry set"). But the hour was late and soon Jenny uttered the words that all children dread.

"Michael it's time to get ready for bed." The reaction was instantaneous.

"NO!" Michael was up faster than Sherlock or Jenny could move. The toddler scurried around the apartment, knocking over whatever he could reach on his way to hide under the kitchen table. The two adults stood, baffled.

"Well, what now?"

"I don't know Sherlock. Does Mary have this much trouble?"

"Of course not, but then again Mary is his mum."

"True." Jenny thought hard for a moment.

"I have an idea. Pull out his night clothes and I'll get him out." Sherlock looked at his neighbor quizzically before going to oblige.

"Michael?"

"Don't wanna go to bed!" Jenny rolled her eyes.

"That's okay honey. You don't have to; I just need you to come out from the table."

"NO!" The young woman sighed.

"Michael, do you want me to sing you a Christmas song? The toddler nodded his head. "Okay, well first I need you to come out from the table and let Uncle Sherlock put your pajamas on you." Michael hesitated before complying. Sherlock looked grateful and quickly got Michael changed. After which, Michael crawled into Jenny's lap.

"Now, which song do you want to hear?"

"Drummer Boy!" Michael had recently seen the old Claymation film and was obsessed. Jenny nodded and was about to begin singing when Michael interrupted. "Uncle Sherlock, play please." Sherlock chuckled and pulled his violin from the end table, obviously having prepared it before hand. He nodded to Jenny as he struck up the first stain of notes for the old carol.

Michael's eyes where beginning to close, the combined sound of Sherlock's violin and Jenny's voice calming him considerably.

Mary nodded

By the time the final verse ended, Michael was sound asleep. Jenny scooped him up and placed him on the bed in the spare bedroom. She sighed and she turned to pick up what Michael and tipped over.

"Jenny, don't worry about that. He didn't break anything." Ordinarily, she would've argued, but the episode with Michael exhausted her.

"Thank you for helping with the song." Jenny turned to her friend. "It really made a difference." Sherlock shrugged.

"You had the idea. Quite an impressive one actually." Jenny smiled.

"Why thank you." She popped open her computer to study some of her lines for the next day's rehearsal.

"What do we tell Mary and John?" She looked up.

"We tell them that he was a little angel." Sherlock nodded and the two neighbors settled into a companionable silence.

Okay, so not super Christmassy. But there will be plenty of that in coming chapters. Hope you all enjoyed! – Endurance
