The Odd One out – Chapter 1

(Erica's POV)

I walked up the wet street, the hood from my black raincoat pulled up and my head pulled back inside with my headphones in. I couldn't take another car journey of dad and Leo arguing about gadget confiscation and Justin pining over Kenzie.

Between Justin kicking off last term and Leo being weird this term I kind of felt invisible to my dad, I spent most of my time in my room with my headphones trying to block out the arguing. I missed my mum, we got to see her on weekends and at school but it wasn't the same.

Sometimes it just felt like I was a complete outcast in my family, everyone in my family had dark hair, dark eyes and were generally opinionated. I on the other hand had blonde hair and dark eyes and tended to keep out of the way. I didn't look like either of my parents but I guess I'd always just ignored the fact.

I knew it could happen sometimes.

I was kind of the nerd of the family and it was rare if I was seen without my computer or a book in my hand. My grades never slipped below A's yet it had become such a frequent occurrence that my parents didn't notice anymore yet my brother's got praised if they got through the day without ending up in the cooler.

I didn't really care anymore… Sometimes I wished my parents noticed more but other times it came in handy. I had nothing else to do but study, I didn't really have any hobbies and I was kind of a loner. I didn't really like being around people, I preferred being alone.

I reached school still in my own world and bumped into a girl with long brown hair and hoop earrings, annoyed she slammed her hands into my shoulders and I fell backwards onto the concrete.

"Watch where you're going swot" She said in a strong Scottish accent, before her and her friend laughed.

"Oi you two! Cooler now!" A voice shouted from further down the drive

The pair groaned in frustration but went inside.

A blonde woman approached me and helped me to my feet.

"What's your name?" She asked

I wasn't really supposed to talk to strangers but she looked like a teacher and she was on school property and she knew what the cooler was so I guessed it was okay.

"Erica" I answered

"I'm Miss Hutchinson, the new deputy head" she replied with a smile "Come on let's get you cleaned up" She motioned to my hand, which I hadn't even realised was bleeding.

She led me into dad's office which now had another desk in and pulled out a first aid kit.

(Lorna's POV)

The cut wasn't too deep but I dragged out patching her up so I could get to know her a bit more.

"So, do those girls hassle you a lot?" I asked

"Not really, it was my fault I wasn't watching where I was going, I was in my own world" She replied

She winced as I gently wiped over the cut with an antiseptic wipe.

I watched her face as she did so, she had beautiful chocolate coloured eyes and her soft face was framed by loose blonde curls just as I remembered her.

It had taken me so long to find her, I just wanted her to stay with me all day and talk. She was so sweet and kind, I wanted to hold her so tightly and never let go.

I finished dressing her hand just as the door opened and the head walked in.

"Ricky, what are you doing here?" He asked

"Oh nothing just-"

"-Good, if you see Leo tell him to come and see me" He instructed as he walked around and sat at his desk

I saw the expression on her face as her heart sank.

"Yeah dad…" She replied, before picking up her bag and turning to face me "Thanks Miss"
