Why Didn't You Tell Me?

I told you

-----James' PoV----
The fact Casey wants a DNA test done over Jess has really annoyed me! They look so much alike it's unreal and I know he made my little sister up set by saying that I could tell!
He needs to grow up and realise he's a dad now not the young flirtations teenager who can do any girl and get away with it!
He had sex with MY sister.

-----Chloes PoV----
Today's the day me and Jess make our way to the clinic so we can get a DNA test done for Casey.
Casey offered to pick me and Jess up but I said no because it would be so awkward!
Today was a right struggle! I mean normally I take the kids to their little play group and Jemma goes and sets the shop up waiting for our customers but because of the time we have for the test I couldn't take Logan to play group for her, she asked James to take him for her which he happily agreed on!
She would have asked Jake to take him but he done something really bad...
Anyway it's 9 clock and I'm with Jess waiting for Casey.
He spots me and smiles at me then quickly frowns and Jess he's going to regret that when he finds out he's a dad!
"Hello Chloe! Hello Jess"
"Hi dada" Jess said.
Some how that made Casey smile so much...
"Ready??" I asked Casey I got a nod in return.
We walked in to the click and I said we was here with in a couple of minutes we was called.
"Hi I'm Doctor Nancy and I'll be doing your appointment today because I run the DNA test part" she started saying.
"I can tell you both don't want to be here that much so we are going to do it quick and simple, Casey put this ear bud in your mouth and twirl it on your cheek please."
He did what she said.
"Okay now Chloe can you do the same just for Jess please."
I did what she said and handed it back to her.
"Thankyou very much I'll get your results back in about an hour I thought because you both seem like busy people I'll do the fast test for you." she said smiling.
"Thankyou so much!" I said.
We had an hour to wait so we went to the local cafe to get something to eat and drink.
I had just a cup of tea Jess had a chocolate muffin and orange juice and Casey had pancakes and a cup of tea.
The hour went fast to be honest we headed back to get the results.
"Hello again I have your results if you'd like to follow me." Nancy said.
I placed Jess on my hip and followed the doctor.
"Okay so the results came back that in fact Casey you are Jess' father." she said.
Casey's face brightened up.
We left and I had to head to the play group to drop Jess of them go to work.
"Erm I'll text you" Casey said.
"Alright Casey see ya" I said.
"Bye Jess" he said kissing her forehead.
"Bye dada!" She said.
I dropped Jess of the the play group and headed to work.

-----Jemma's PoV-----
Today's been rubbish already I just can't get it out of my head!
I hate him!
"Jem I'm here" Chloe said.
I wiped my tears and went to see her.
"Hello" I said.
"Babe I know what Jake done was bad but we have to get through it alright."
"Okay" I said.
Why did he do it??
