Guess what everybody! Third part is up. Now this most likely will be as far as I go. I didn't expect it to get farther than the first chapter in the first place. Please oh please leave me a review. This is my most popular story for only having two chapters and about twenty reviews. Thank you everyone! Now enjoy! :D

I have no claim to Young Justice. If I did, this would have happened a long time ago…

"I thought you had to write a paper," Artemis replied, smirking at her boyfriend who was playing with her niece.

Wally shrugged. "A small break doesn't hurt. It won't take long to finish." He built a tower using Jenga blocks only to have Lian gleefully knock it over. "Besides," He added, starting a new tower, "I didn't think you'd have Lian again after barely a week since her first stay."

"Jade trusts us enough to take care of her, I guess." Artemis merely replied while drying their dinner's dishes after washing them. Jade came by a few hours previous, promising to be back by the morning, latest. Artemis wasn't going to question her sister's activities for now.

Hanging up the dish towel, Artemis walked over and picked up her niece. "I'm going to get her ready for bed while you work on your paper."

Wally grinned as he stood up. "Whatever, babe. Don't lay her down yet though."

"Hurry up then," She remarked. He lightly squeezed Lian's hand and promised to build more with her soon. Artemis smiled as she carried the baby to the bathroom.

Artemis soon finished bathing Lian and carried her back out when she heard voices in the front room.

"Just thought that we'd drop by for a quick visit."

"And he thinks you have his Back to the Future collection." A younger voice added.

"Hey, you said that you've never seen the movies and thought that you would like them even though their calculations are a bit off." The older shot back.

Artemis walked in to see Barry and Bart in uniform, the younger snacking on an apple that he took from the fridge. The blonde gave a greeting gesture which Barry smiled in response before briefly pausing and turning back to his nephew.

"Wally, do your parents know about this?"

"Know about..." Wally noticed his uncle's gaze at the baby in Artemis' arms and immediately understood. "Oh, no. We're babysitting."

"And who would let you watch their kid?"

Wally took offense. "Hey, I can be responsible enough. She likes me."

Bart studied Lian before his eyes went wide in recognition. "Oh," He clamped his mouth shut and avoided looking at anyone in the eye.

"What is it Bart?" Barry asked.

The future speedster took another bite of his apple as he shrugged it off as nothing. "I just remembered I need to do something when we get back."

"Kid, I know the Allen family look very well." Barry replied, not convinced as he folded his arms.

Bart turned to the couple for support when Barry's cell goes off. The eldest speedster answers before anyone had a chance to say anything.

"Hey Ollie, did you know that Artemis and Wally have a baby?"

"What?!" Is heard loud and clear from the other line. Soon, the phrase was repeated.

Barry continued explaining, "They say that they are babysitting, but apparently they are keeping it quiet."

Wally's arms were flailing. "You didn't even give us a chance to explain!"

"Yeah, hang on," Barry said through the phone before raising his eyebrow at them. "Well? Ollie is demanding answers as are Dinah and Hal."

Artemis groaned. Of course, Ollie wouldn't be alone when something big was said. He must have been in the Watchtower. The news was sure to spread like wildfire now.

"Roy is going to kill you if you say," Artemis quietly said to Wally while shifting Lian in her arms.

"What does this have to do with Roy?" Barry asked while still on the phone. On the other line, they could hear inaudible speech from Ollie as he ranted on. There was a stare down between the three as Bart watched from the side, smiling as he wondered how they were going to get out of this one.

Artemis was the first to break the silence. "Here," She said as she gave Lian to Wally. The blonde walked up to Barry and held out her hand. "Give me the phone." Barry complied as he silently obeyed. Artemis turned and stared between Barry and Wally as she spoke into the receiver.

"Ollie, listen. Since Barry decided to stick his nose into someone else's business, let me clear this up. We are babysitting my niece, Lian. Roy's daughter." It was completely silent on the other end. "Hello?"

Barry stayed quiet as Bart grinned, going up to Lian to greet her by name. Another moment passed and as Artemis was about to hang up, she heard movement.

"Mind explaining why Ollie has been staring at the wall?" Dinah asked.

Artemis sighed. "He just found out he's a grandpa. That's all. Lian. She's Roy's and Jade's."

Another pregnant pause. Finally, Dinah asked, "Can you send pictures?"

Once Ollie got over the shock, he took part in enjoying the pictures, while asking to see her in person. Artemis told him to ask Roy about it since it wasn't her place. Ollie vowed to once he got the chance. That promise was soon kept. At least the news wasn't spread too far before the archer mentor talked to his adopted son. Dinah said that Ollie couldn't have been happier to see his granddaughter. Now to explain the joking manner Barry used to tell Wally's surprised parents and aunt about Lian…

BONUS!

Epilogue: 3 months later…

"Are you sure you don't want anything else for breakfast?" Wally asked again as he flipped an egg.

Artemis chuckled as she gave him a kiss on the cheek. "I'm stuffed Wally. You've been spoiling me too much since I've been back."

"That's because I'm glad you're finally done with that undercover gig. It's lonely eating alone."

Artemis clasped her hand with his and squeezed tightly as she leaned in the crook of his neck. "I missed you too, but lighten up a bit on the food please. I can't eat as much as you."

Their moment was shortened due to a knock at the door. "Wonder who is coming by to visit this time." She mused aloud. Only her second day home and already she had a visit from Zatanna, M'gann, Connor, and had a long talk with her mom, Dick, Babs, Raquel, Ollie, Dinah, Billy, and Barry. Artemis opened the door and took a step back in surprise.

"Jade," She smiled and embraced her sister who returned the gesture. Artemis was so used to giving hugs lately that she didn't think about it. "Glad to see you know how to use the front door for once."

Jade rolled her eyes. "Red made me,"

Artemis' eyes brightened when she saw Roy holding Lian. Artemis gave him a one arm hug.

"Glad to see you made it through," Roy replied with a small smile.

"Thanks," Artemis looked down at Lian. "She's getting so big!" Lian happily reached for her aunt until she was passed over.

The two couples and baby spent the rest of the morning catching up. Wally remained at Artemis' side her hand in his, as Lian sat in front of her playing with blocks. Already the baby chucked a few at Wally for fun target practice, earning laughter from the others.

"The Great One," Jade replied while rolling her eyes, "Will return for another day."

Artemis took a sip of lemonade from her glass. "Goodie," she added sarcastically. Through her sister's insider information, Artemis was glad to at least put a stall to the Light and Reach, but no one knew for how long that would last.

When it was time for them to leave, Artemis and Wally made sure to give Lian a hug before handing her back to her mother.

"You know," Jade began with a sly grin, "Since you're back, you will be able to babysit more."

"Thanks Jade, but as much as I love Lian, at least let me enjoy some time off."

"Alright then. Later sis,"

Artemis sighed as she brought the empty cups of lemonade that was served, in the kitchen.

"I think that was the first time your sister didn't insult me in some way." Wally replied as he brought the rest of the cups. "And it was nice to see you so happy to see them."

Artemis began filling the dishwasher. "I don't know if they realized, but having Lian has done better for the both of them."

"Ever think about having kids?" He asked.

She had her back to him as she dried her hands and took her time to respond. "Sure, after a while. Not until after we're married…" Artemis turned around and couldn't help gasping. Wally had gotten down one knee with a small black velvet box in his hand. "Wally," She cooed, her hand to her mouth as her eyes softened.

"Artemis, as cheesy as this may sound, I spent the hardest three months with you gone, worried sick how you were handling. I'm not ready for more. Dick nearly gave me a heart attack a couple of times." He opened the box and revealed the ring. "I actually had this for a good while and kept holding off… until now. Artemis, please?"

"Please, what?" She sputtered out, smiling.

He lightly laughed. "Artemis, will you marry me?"

"Of course, Wally. Yes." He put the ring on her finger and joined together in a blissful kiss. When they separated, Artemis breathed out, "This isn't just about having kids is it?"

Wally shook his head as he smiled. "That can wait as long as we want. Just the two of us for now."

He grasped her left hand, tracing over the ring on her finger. As their lips touched once more, Artemis beamed inside. This was by far the best surprise she had gotten yet, and she couldn't wait for more.

Hope you liked the little bonus at the end! This is the third or fourth time in a story the idea of marriage was brought up for these two. They are meant for each other and I really hope that they do officially get together soon after that recent episode.

It will be a very sad day once the last episode comes around. Why just one more?! After "Summit", I had lots of feels and had to refrain from jumping up and down when Wally donned the costume and had Spitfire was reunited, hence why I had to add that last part instead of as a separate story.

And a small note, I have never seen any of the Back to the Future movies. Review!
