Sister Secrets by Titania Woods

Jade knows all the answers in class.’
    Then her smile faded as her thoughts returned to Teena. ‘So you think – you think it was really Teena I saw?’ she said slowly.
    â€˜Definitely,’ said Ivy. ‘Think about it – you only saw her in shadow, and the back of her head. So how did you know it was Zuzu?’
    â€˜Because . . . she was wearing Zuzu’s hair clasp,’ said Twink feebly. Oh, it seemed so obvious now! No wonder the fairy hadn’t turned to face her. It had been Teena !
    â€˜There, you see?’ said Ivy. ‘She knew you’d think she was Zuzu, because she was supposed to be Zuzu – and then your mind filled in the rest!’ She bounced up from the table. ‘Anyway, I’m meeting Jade at the tuck shop. Remember your promise, you two, all right?’
    Twink and Bimi agreed – and then glanced at each other worriedly as Ivy flew from the library.
    â€˜So it was Teena!’ breathed Bimi. ‘But why would she do such a thing?’
    Twink’s chest felt tight. ‘I bet Zuzu put her up to it – and Summer, too, for that matter. Zuzu probably planned the whole thing! And Teena went along with it.’ Pulling the petal towards her again, Twink started scribbling lines as fast as she could.
    â€˜But Twink, you don’t know that,’ protested Bimi. ‘I think you should talk to Teena, and find out what really happened!’
    Her best friend had a point. Twink looked down, playing with her snail-trail pen. ‘All right, I’ll talk to Teena,’ she said finally. ‘Maybe – maybe there’s some explanation.’
    But she didn’t believe the words, even as she said them. Teena had pretended to be Zuzu just to get Twink into trouble. Hurt anger stuck like a stone in Twink’s throat. How could her sister explain that?
    â€˜Oh no!’ gasped Teena in dismay. ‘Is that why you didn’t follow me into Snowdrop Branch? We didn’t know what had happened!’
    â€˜So it was you,’ said Twink bitterly. It pained her to have Teena admit it, even though she’d known it must be true.
    The two sisters were hovering outside the main entrance to the tree, where Twink had caught up with Teena after Flight class. Teena nodded, hugging her petal bag. ‘It was only meant to be a joke, Twink!’
    Twink stared at her, hardly able to believe her ears. ‘A joke ? To have Mrs Lightwing catch me?’
    â€˜No!’ cried Teena. ‘We didn’t know she would. We just thought you’d come in the window after me, and then you’d see that Zuzu wasn’t even there , and you’d realise –’
    â€˜What?’ burst out Twink. ‘That she’s a really bad influence on you? Because she is , Teena – I’ve never known you to act this way before!’
    Teena’s eyes grew wide. ‘But – but I didn’t do anything really bad,’ she whispered. ‘Neither did Zuzu. We just wanted to show you that –’
    Deep down, Twink knew she should listen to what her little sister had to say. But then she thought of Zuzu’s smug, cheeky face, and she felt on fire. Oh, Zuzu must be having a great time sniggering at Twink now! And here was Teena defending her.
    â€˜Well, don’t worry, Teena – I’ve had enough of trying to help you!’ she interrupted coldly. ‘You and your precious Zuzu can stay friends, for all I care!’
    â€˜But you don’t understand!’ wailed Teena, her eyes bright with tears. ‘It was my idea, not –’
    Twink didn’t hear. She had already flown back into the school, her pink hair whistling behind her.
    Teena hovered by herself, staring after Twink. She couldn’t blame Twink for being angry about the lines, but she hadn’t even given Teena a chance to explain! She’d just stormed off without listening.
    Shakily, Teena wiped her eyes. Well, if Twink had
