I don't know if Lucy knew about Peter's secret, so for the sake of this one shot, she doesn't... Until now :)

Enjoy X

Peter hadn't known what to do when it had happened, but once he got his mind together, he knew where he had to go. He arrived back on the Square and headed to his Dad new restaurant. He pulled the door open and stepped in, looking round. He tried to find his Dad, when he heard it. Arguing. And their was only one person he knew who could argue that fast and not take a breath.

'Is this a private party or should I open the door for everyone to hear?'. The second Peter had spoken, Lucy voice stopped and she smiled. After that, she was happy as larry, smiling and talking and a lot calmer. That lasted until he entered the Beale household with her and Ian and her happy mask slipped.

'What the hell are you doing here?' she spat. Peter took a step back at his sisters sudden vocal attack, but composed himself.

'I've missed you... And Dad and Bobby' he added, though he knew he wasn't fooling anyone, especially not his twin.

'Right. Hot chocolate anyone?' Ian asked, oblivious to his son and daughters argument. Lucy rolled her eyes and pushed past Peter, heading up the stairs to her room, slamming the door shut behind her...

Lucy awoke sometime in the night, coughing. She threw her comforter off her and headed downstairs for a drink. She used the moonlight in the kitchen to guide her round. She filled the glass with water and headed into the living room. She sighed and let herself drop o the sofa, letting out a small shriek of shock and scrambling to her feet as hit an object. Light suddenly lit the room and Lucy put a hand to her heart.

'Jesus! Peter, what are you doing?' she hissed to her twin, who sat up, rubbing his eyes with the back of his hands.

Ugh! I feel asleep. What time is it?' Peter asked. Lucy sighed and sat down.

'Half past three in the morning' Lucy said. She took a sip of water, before she spoke again.

'Why are you up so late?'

'Couldn't sleep. What about you?' Peter asked, grabbing the glass from Lucy hands and taking a sip of the water.

'Coughing fit' Lucy said, rolling her eyes at how lame her excuse sounded. Peter chuckled softly besides her and she took back her water. 'Why couldn't you sleep?' she asked, taking a long drink.

'I killed someone' Peter blurted out, before instantly regretting it. Lucy choked badly on her drink and it sprayed over the table. She entered another coughing fit and smacked her chest, as Peter panicked and hit her back repeatedly, until she held up a hand. She turned to face him, looking horrified.

'You what?' she said, only just managing to keep her voice down.

'I killed someone' he repeated, locking eyes with his twin.

'Who?' Lucy whispered

'Gaz' Peter answered, watching as Lucy's horrified expression grew. He knew she was about to panic, so he grabbed her hand and urged her to keep quiet.

'How?' Lucy asked, once she had gotten herself under control and calm. Peter swallowed and looked away, causing Lucy to grab his chin, with her free hand, and forced his head to face her again.

'We had a bonfire on the beach, a little party, just mucking about. I woke up and... I woke Gaz up too and I convinced him to go for a swim in sea with me. We were fine, until Gaz said he was feeling tired. We were still drunk, so I tried to convince him to swim back to shore, but he said he was too tired to swim... That's when the current tide came in. We tried to swim against it...We did, Luce. We really tried. But it was too strong, too strong for Gaz. I swam back to shore and ran to find help after waking the others up, but I was too late... I was too late!' Peter sobbed, feeling the tears roll down his cheeks. It didn't help that Lucy's expression hadn't changed from horrified. He began to panic and tried to escape, but Lucy yanked him by the hand and he sat back down, facing her.

'You convinced him to go for a swim? He had a choice. He choose to say yes, but he still had other option of saying no. He choose to get in water, knowing he was still drunk. You may not have felt drunk at that time because you had only woken up, but he still had a choice. You did't kill him, Peter. You didn't. I mean to sound mean, but... He signed his own death certificate by getting that water at his own choice' Lucy said, her eyes locked onto her brothers, making sure he got the point. Peter sniffled and allowed the last few tears to fall, before pulling to him and into a hug.

'Thanks. For letting me tell you... They blame me, which they have a right to. I mean, I killed their friend...' Peter whispered.

'Is that why you really returned? Not because Dad invited you?' Lucy asked. She felt Peter nod on her shoulders and he hugged her tighter, thanking Lucy for listening.

'I'll always be here for you. No matter where I am' Lucy said, causing Peter to draw away from their hug sharply and grab her shoulders.

'What does that mean?' he gasped

'It's a figure of speak, Peter. I'm not going anywhere' she laughed gently, causing Peter to smile. Lucy let out a big and rested her head on Peter's shoulder and settled down to go back to sleep, pulling the sofa throw over them both.

'Luce, I'm not a pillow! Get upstairs!' Peter said, looking down at her.

All he got for an answer was a slight snore...
