When Meredith returned from checking on the babies - who were still fast asleep - she found Addie curled up in their bed reading a book.

Sighing, she pulled her hair out of the tie and let it fall around her face. She wasn't sure if she wanted to get into bed with her or not. She still felt as though Addie was lying to her.

She absently looked at the bed, or more so, her space in the bed. I appeared that Addie really did think that they would be sleeping together tonight.

"You can jump in, I won't bite." Addie told her as she glanced up from her book.

Meredith rolled her eyes at her; trust her to joke while they were in this situation.

Meredith watched as Addie closed up her book and took off her glasses before looking at her pointedly. "Just get into bed." Addie told her as she too loosened her hair.

Meredith inched towards the bed until she was standing directly beside it. "I don't think I can share a bed with you." She told her before sitting down on the beds edge this time she couldn't bring herself to look at Addie.

"Meredith please." Addie said quietly, her voice slightly strained.

"I can't Addie." Meredith replied. "The last time we slept in the bed together I thought we would be together forever."

"And we can." Addie said as she rolled onto her side and contemplated whether she should reach out and touch her.

"Not when you hide things from me." Meredith murmured.

Addie took a deep breath before letting out a sigh. "I intended on telling you this afternoon Mer." She told her "but you don't sit still long enough and there is no easy way to say this."

"What?" Meredith asked as she now turned to look at her.

"The house" Addie said as she tried to keep a calm voice. "My promise to dad."

"Yeah" Meredith said weakly.

"Is because they are scared that the cancer will come back." Addie confessed. "And if it does, and something happens, they want to know that both you and the kids awe looked after. That you will have a safe roof over your heads."

"But" Meredith started, hating the very thought of Addie being sick again and being gone for good. Tears were welling in her eyes with the thought.

"Now you see why I didn't want to tell you in front of Olivia and Elliot? Because I didn't want to worry them."

Meredith sighed as she looked over at Addie. "Do you think you are going to get sick again?" She asked.

Addie shrugged her shoulders. "Do you?" she replied.

Meredith too shrugged her shoulders not wanting to think about either of them being re diagnosed.

My happiness.... my happiness... my happiness.... my happiness....

She had thought that spending the night back in her partner's arms that she would have had peaceful dreams, but the nightmarish flashes on her future had been enough to keep her tossing and turning all night.

Now as she rolled over expecting to see her wife, she found the bed empty and felt her heart begin to speed up, trying not to panic.

She looked around the room hoping to find a clue as to where she might have gone, but on finding nothing, and noticing that the baby monitor was also gone, she began to panic further.

Scrambling out of bed, she neglected any foot wear and began the dash to the baby's room. She had no idea why she was looking there, but she figured that it was instinct.

Finding the cots bare, the knowledge that the babies were gone tore through her and she did not know what to do. She didn't want to assume the worse, but she wasn't sure what else to do.

Her heart began beating furiously against her chest, her mind began racing, trying hard to think of the places where they could be, and too scared to consider that she could have taken the babies and ran.

Moving down the stairs she began to call out to Addie, hoping that she would answer her.

She ran down the hall, looking in to the rooms, hoping to catch a glimpse of them.

It wasn't until she reached the gym room that she found them. It seemed as though Addie was doing what used to be her regular morning workout. She had her iPod plugged in and she was jogging to the music.

The babies were all seated in the chairs directly in front of the treadmill so Addie could keep an eye on them.

Meredith let out a sigh of relief as she entered the room, moving to kiss all 4 babies. She then looked at Addie who had a smile on her face.

Meredith moved towards her and watched as Addie flicked off the machine and reached for her sweat towel.

After Addie had wiped her face over, she completely took in the look on Meredith's face.

"Mer" she asked as she stepped off of the tread mill and moved towards her.

"Don't leave."Meredith murmured as flashes of her dream came back to her. "Don't leave me again."
