A few weeks went by and Meredith's labs came back positive. Her body wasn't rejecting the new pair of lungs and she was finally cleared to go home again

Meredith's lung capacity has improved a lot in the past week and she's good enough to walk down the hallway and back to her room

"Mer, you're cleared to go home" Bailey said as she stepped into the room where Meredith, Derek and the kids were playing a board game

"Well, as long as McDreamy keeps taking care of you" Cristina added

"Of course I will" Derek whispered before kissing Meredith's lips

"Daddy!" Bailey groaned

"Even the McBabies don't like your kissing" Cristina laughed

"I'm happy I can kiss him again without feeling like I'm breathless" Meredith giggled

"You still need to take it easy. No lifting, no workouts, no climbing the stairs unsupervised and I'll write down the rest if the rules" Cristina said with a stern face "Oh and don't die" Cristina added with lifting her eyebrows

"Mommy?" Ellis whispered "You're not gonna die, are you?" The little girl asked

"Of course not" Meredith said and kissed the little girl's head before looking at Cristina with a frown

"I'm sorry, I- I didn't mean it like this. You mommy's gonna be fine, I-" Cristina started to panic when she saw the crying young girl

"Aunt Cristina is really bad at making jokes, baby. Don't listen to her" Meredith told her daughter with a smile who seemed convinced and nodded before repositioning herself in Meredith's arms

"We're gonna give you some time to pack your stuff" Bailey said and left

"Mer? I- I'm leaving in a couple of days, I'm sorry" Cristina said before leaving the room

Meredith nodded even if Cristina already left and hugged the little girl that was laying in her arms even tighter

Derek noticed that Meredith felt bad about this and quickly moved closer to her and wrapped his arms around her

"I'm fine" She whispered

"I know" Derek whispered back but didn't let go of her

"Thanks for sticking with me" Meredith whispered while looking into Derek's eyes and leaning a bit closer into his embrace.

"I wouldn't trade any of this, ever" He whispered back and kissed her head

"I should finish packing.." She sighed

"Let me. You go cuddle with the kids" He smiled at her and she nodded

Derek got up and grabbed her bag that was already partly packed. He walked into the bathroom to grab her toothbrush and toothpaste, a few of her other stuff before returning to the room and grabbing her sweatpants and sweaters and stuffing them in her bag

"Come on guys, let's clean this up" Meredith said as she tried to get up but her body protesting at this

"Mommy, you need a hand?" Zola asked and Meredith grabbed her oldest daughter's hand and pulled herself on her feet, swaying a bit

"Mommy, sit down. Me and daddy will get everything ready" Bailey said with a proud smile on his face

Meredith and Derek had to chuckle a bit by seeing the kids care for their mom

"I think we should let daddy stop at McDonalds" Meredith laughed

"I want nuggets!" Ellis yelled

"Can I have a large menu?" Bailey asked as his eyes grew

"I want a strawberry milkshake" Zola gasped

"And I would love some French fries" Meredith winked

"I thought you should eat as healthy as possible? Didn't the doctor say that?" Derek grinned

"I can't remember that, besides, fries are potatoes, which are vegetables.." Meredith laughed

"Of course" Derek laughed as he and Bailey finished packing. "Okay guys. I'm gonna sign mommy's discharge papers. Stay here and don't make any trouble" Derek warned them

"Kay, daddy" Ellis smiled and brushed her fingers through Meredith's hair

"Baby, can you hand me my phone, please?" Meredith asked Zola

"Of course" Zola said and handed Meredith her phone

"I'm texting uncle Alex and aunt Jo to see if they wanna come over tonight" Meredith smiled

"Is the baby still in aunt Jo's tummy?" Ellis asked

"Yep, for at least another 5 months, baby" Meredith giggled as her daughter sighed

"That's too long mommy. I wanna play with the baby" Ellis complained

"Soon enough" Meredith replied

"Okay Grey, please don't force it at home" Bailey said as she entered the room, followed by Cristina "Come in if you feel any trouble breathing, if you feel you're wheezing or anything"

"Mer, I'm coming by tomorrow to say goodbye. Is that okay?" Cristina asked

Meredith nodded "Alex and Jo are coming over tonight. You can join if you want"

"Oh, no.. I- I have a surgery and I, yeah.." Cristina sighed "I'll see you tomorrow" She said before leaving the room

"Okay" Meredith whispered but Cristina was already gone

"Mommy, let's go" Bailey grabbed her hand "We need ti go home"

Meredith and Derek had to giggle and Derek helped her into the chair
