Rob and Louise pulled up outside the office after their first scan.

"Are you ok?" Rob said as he turned the engine off and faced Louise.

"Yeah, we've just had a fantastic holiday why wouldn't I be" Louise half smiled not taking her eyes of the scan photo.

"Well I noticed that you didn't once look up from that photo" he placed a hand on Louise's knee as she put the photo down.

"Well that is very observant of you, maybe you should be a detective" Louise joked.

"I know it's daunting becoming a parent but honestly I couldn't think of anyone better to have a child with, shall we go show our faces then" Rob kissed Louise's forehead and got out of the car.

"Where is everyone Gerry?" Louise walked in and was greeted with open arms from Gerry whilst Brian was busy on his computer.

"Oh jack and Sandra are in an interview room at the moment, Fancy a cuppa?"

"Please" Rob and Louise said in unison.

"So have you been behaving yourselves?" Rob looked over at the bored.

"Never " Gerry chuckled.

"How was the holiday?" Brian muttered from behind a screen.

As much as Louise tried to focus on anything other than the scan, she missed what Brian had asked.

"It was great just what we needed" Rob said

"I'll be back in a minute" Louise said to Gerry as she toke her tea with her.

"Is she ok?" Gerry turned to Rob with a concerned look.

Louise waited outside the interview room for Sandra

"We'll be in contact if there's anything else Mr Knight" Sandra and jack watched as their prime suspect walked away from them.

"Mum, is now a good time?" Louise could see that Sandra looked disappointed

"Oh hello sweetheart" she grabbed hold of Louise for a cuddle, "it's just one of those days I guess"

"Can I have a word" Louise pointed to the interview room and they both entered as jack walked away.

"What's up?" Sandra couldn't look happier with the fact her daughter was home.

Louise slid the scan photo across the table as a tear rolled down her cheek.

"You're not, are you?" Sandra looked from the photo to Louise and back.

"Im 4 months, I wanted to tell you before he told the others" Louise couldn't look at Sandra whilst they spoke about it because she knew her mother would be able to see how she felt and she was right.

"This isn't what you want is it?" Sandra felt as if history was repeating itself.

"It wasn't planned but Rob seems happy" Louise wiped the tear from her face and put the photo in her pocket.

"I didn't ask about Rob, I asked if this is what you want" Sandra stood opposite Louise and looked at her in the eye.

"I should be the happiest person alive right now but before I saw the scan I was hoping that the tests were wrong and then I saw Robs face and it became real but he's happy and I want to be with him so " as Louise answered she couldn't help but smile.

Sandra gave her daughter a hug and congratulated her but she could still see that a baby wasn't what Louise wanted, no matter how hard she tried to convince herself.

They both returned to the office where the boys were telling Rob about the new case.

"We think it's Marcus Knight but we haven't got anything solid yet" Sandra interrupted.

"Well I'm sure you'll be able to prove who it was eventually, how do you all fancy the pub, I'll meet you over there. Drinks are on me" Rob winked at Louise and made his way out of the office.

Louise just caught Rob before he headed up the stairs. Sandra watched them both as they stood outside the office talking

"Rob take this" Louise gave him the scan photo

"But don't you want to keep it?" Rob said with confusion.

"I've got the others in my bag, I thought you could put it in your office or something" Louise smiled and put her hand on Robs cheek. "I love you" Louise kissed Rob and Rob deepened the kiss both had clearly forgotten where they were but as long as they had each other they didn't care.

"And I love you" Rob kissed Louise on the forehead and walked off.

Louise made her way back into the office.

"There's got to be something we're missing, who's not telling us the truth" Sandra said in an attempt to make it look like they were discussing the case whilst Louise wasn't in the room.

Picking up a statement Louise asked "what time did Marcus Knight and his ex say that he arrived at the hotel?"

"They claim that they left their house at 8pm and arrived at 9:45" Gerry pointed it out on the statement to Louise.

"Well that's impossible, Rob toke me to Poole for our holiday with the kids and it takes at least 2 hours and 40 minutes even when Rob is driving, I mean for a police officer he doesn't half speed, Brian can you bring up all possible routes to the hotel please" Louise said as she walked over to Brian's desk.

"Did you trade him in for someone who isn't a tosser ?" Gerry joked

"Sorry?" Louise was focused on the case.

"Are you sure everything's ok? Because if he's upset you then I'll sort it" Gerry looked concerned.

"Gerry, I'm fine however I'm sure he'll go back being the usual tosser that you all know and love as soon as Monday arrives. But thanks for looking out for me" Louise smiled.

"Anyway Strickland just said that he was buying drinks, so we'd best head over there before he withdraws his offer" jack passed everyone their coats and they all headed for the pub.
