Sorry I didn't update sooner I lost 3 whole chapters and just got really mad with my computer :-)

"Do the girls know that we knew their mom" (Callie)

"Its hard to say, they don't open up much. I would say yes, they knew their moms former partner Mark and Lexie would show them photos." (Liam)

"They knew Mark..." (Callie)

"Yes very well from what I've heard" (Liam)

"If they knew that we knew their mom they would have told us." (Meredith)

"It depends, your the sister of Lexie right?" (Liam)

"Half- sister." (Meredith)

"Meredith right?" (Liam)

"Yes" (Meredith)

"Then yes they know exactly who you are, they've seen photos and heard stories from they mom" (Liam)

Arizoma Butts in

"So why wouldn't they tell us" (Arizona)

"They might not neccasarily want us to know. Until they admit that their names are Lily and Sarah Grey, we have to legally keep searching for their identities. Although I've known them since they were a week old and will be willing to bet my life on the fact that it is them. Social services can't legally add a child to a group home facility until it had been that the girls are orphaned or homeless." (Liam)

"How does that help them." (Callie)

"It means we have to keep them in foster care until their legal documents and fingerprints have been tracked down. Nobody likes group homes but not every person in the world is willing to take in kids they don't know. They're done this before." (Liam)

"Their smart thats for sure" (Meredith)

"Yes incredibly smart... they've just been through a lot of hard stuff" (Liam)

"Yeah... I can't imagine" (Callie)

Derek Bursts through

"Mer, I got your page whats wrong" (Derek)

He spots the two girls playing with Zola and Sofia in the other room

"Oh you found them... are they twins?" (Derek)

"Yes but thats not what we need to talk about!" (Meredith)

She pulled him aside to the sofa area in the day care centre

"This is all going to come out really fast and sound ridiculous" (Meredith)

"Okay?... um go on then" (Derek)

"Ok well, Lexie got pregnant when she was fifteen. She had identical twin girls called Lily and Sarah but had to give them up for adoption although used to see them often and was really close with the girls. The twins were later adopted by people who lived up north until their stepdad left and the stepmom died. When Lexie died they were 10 and were living with their foster mom Melissa, but she died about an hour ago." (Melissa)

"Your right that sounded kind of insane... So those girls are really our nieces?" (Derek)

"Yeah I guess but they were also friends with Mark? Did he ever mention it" (Meredith)

"Not that i remember. Whats happening to the girls now." (Derek)

"They won't sign any papers that will prove they are orphaned because they don't want to be put in a group home" (Meredith)

Arizona runs in

"Sorry to interrupt but they just got a 911 downstairs and your both needed." (Arizona)

An hour later

"Hi" (Callie)

"Thanks but the way... for not lying to us about Melissa." (Sarah)

"What do you mean?" (Callie)

"Well everybody just says that she might wake up...your the only one being realistic here. It's been 3 hours she would of been declared dead by now." (Lily)

"Why didn't you tell us your mom worked here" (Callie)

"My mom was a english teacher at a little school about 2 hours away." (Sarah)

"Your biological mom, Lexie Grey. You knew mark too right?" (Callie)

"How much did Liam tell you?" (Lily)

Hope you like it! Im going to end it there because I don't like going over 650 words per chapter xo
