Disclaimer: I don't own Fringe or its characters but I DO own Olive, Mason, Caitlin, Charlie Bishop and Rachel Lee in this fic...you'll meet the characters later on in the fic.

Olivia glared at Peter and took the twins as Walter took Alex, all five headed down to the basement. Peter looked at Anna, Lincoln and Charlie. "So are we ready to do this?"

"You mean shoot up your house, trying to prevent a madman from taking a kid that could destroy an entire universe and make sure that Liv doesn't go into labor all in one while fighting who knows how many shapeshifters?" Charlie looked at Peter, "yeah we're trained for this, I mean its Fringe Division…prepare for the worst and hope for the best."

Lincoln and Anna looked at him, he shrugged. "Like old times, the three of us."

"Without Charlie stopping mid-fight to get rid of worms." Anna chuckled, "admit it, you miss them."

Charlie angled his head as he always did to crack the joints, "for once I can honestly say the words…hell no!"

"Ahh and here I thought you'd end up marrying one of them." Anna chuckled and looked at Peter, he was eyeing them strangely. "Sorry, we joke before a fight…relieves stress and tension and helps us focus better."

"Whatever works," Peter looked around the kitchen, "Liv has all the weapons upstairs in a safe."

Charlie put a hand up, "I'll go, what's the combo?"

"1986, it's the year she and I met for the first time, long story behind that. Anyways, grab whatever you can and get down here again."

By the time Charlie made it upstairs, the front door was being kicked in as was the backdoor. Lincoln suggested they stand back to back in a circle and they did, Peter found himself face to face with his biological father.

"Hello Son."

"I'm not your son." Peter looked at him, "I'll never be your son…not after what you did to Olivia and my children."

The Secretary eyed him, "speaking of my grandchildren, where are they?"

"Go to hell!"

"Anna, Lincoln!" Charlie stood on the stairs and threw them guns, he threw one to Peter too, who pointed it at the Secretary. Anna did as well as did Lincoln, the Secretary smiled and looked at Anna.

"Olivia it's good to see you again, how is my grandson?"

"Where you'll never find him you bastard and he's not your grandson…he's not Peter's son and so he has no relation to you. I know what you did, almost killing me and Alex because you wanted his blood to test. You could've at least realized I was a carrier for VPE before you decided to do what you did."

The Secretary eyed her, "at least you know now, you can't have more children."

"Oh I can, because they removed the VPE gene from my DNA…I'm perfectly normal."

He took a step towards her and signaled with his hands, five shapeshifters came at all directions. They all took one, however two got a hold of Peter and he fought them. The guns were knocked away in minutes and they were forced to fight hand in hand.

"Anna!"

Anna looked out of the corner of her eye to see Peter being held down and instantly grabbed for the gun she saw nearby, shooting her shapeshifter before turning the weapon on the Secretary. "Let my brother-in-law go now or so help me I'll put a bullet in your brain before you can utter the word 'stop'."

"No, this ends now," they turned to see Olivia and she eyed them, obviously in pain because her face was contorted. "Get down, all of you…"

"What?"

"Oh shit, get down!" Peter looked at them from where he was, "get the fuck down, hit the floor."

Anna and Charlie dropped as did Lincoln, they stopped fighting and turned to see Olivia creating a bubble of fire around her, it instantly shot out and around the group, taking out those around them. Two of the remaining shapeshifters and the Secretary were burned alive. Olivia groaned and slid to the floor afterwards and grasped her belly. Anna shot the remaining two shapeshifters and hurried over as did Peter, he looked at Olivia.

"Baby look at me," Olivia looked at him weakly, "what's wrong?"

"Labor," Anna looked at him, "she's in labor…Olivia did you do that or Caitlin?"

She looked at her sister, "both of us…I created the fire and she made sure it didn't harm you guys." Olivia groaned and Peter eyed her and the house.

"It's a mess, we need to call the fire department and get you to the hospital."

"I got the Fire Department," Charlie pulled out his phone, "you might want to call Massive Dynamic and Broyles to get this covered up and get Liv to the medical center."

A/N: Next is Broyles dealing with the Fire Department and Olivia goes into labor in a helicopter of all places.
