‘As Leap 2100 can’t exist, maybe he was pretending to leap. Or wasn’t sure which year he was leaping to.’

I’m surprised the words I’m thinking in my head are coming out of my mouth. Ama’s staring at me again. She takes a sip of her tea but makes a face like she finally realises she’s drinking a flowerbed.

‘How did you know his tag was a letter L? For Leapfrog.’

‘What’s a tag?’

‘A graffiti signature. They all have one so people know it’s them. Kwesi was proud of his art. How did you know, Elle?’

‘I didn’t.’ This is difficult. I’m trying not to think about deleting SOS L but I can’t help it. Maybe it was Kwesi who sent me the SOS message from 2048 and signed it L. Maybe he leapt from his Leap 2044 school trip to 2048.

‘How do you know he came HERE?’ I say.

‘Why did you ask if his name began with the letter L?’ She’s raised her voice. She looks angry and sad at the same time.

I stare down at my bowl of cold porridge. I don’t know what to do. I’m scared that Ama doesn’t want to be my friend any more. I want to tell her about SOS L but when I open my mouth, nothing comes out. I stare down at my bowl of cold porridge. Ama is definitely angry now.

‘Elle. Look at me. If you know something, tell me. If you don’t, it’s the same as lying!’ Her eyes are wet. Maybe she’s going to cry.

I don’t want to make Ama cry but I’m scared that Kwesi sent a message to me and he got killed in the future and Ama won’t be my friend any more. My head hurts from thinking about it. Too many thoughts. Too much.

I stand up and walk out of the café, along the corridor to the other end of the building. The door to the Common Room is slightly open. I walk in. I don’t want to talk to GMT or Noon back in the chalet. Not that Noon says very much at all. Season’s stretched out on a sofa, fast asleep. The centre table still has the white cloth from last night, covered in cake crumbs. I lift the cloth and sit down under the table. This = having my own special tent. I wish we were camping and not staying in Hive 1. Hive 1 has too many smells in it, deodorant, hairspray, Noon’s Chanel No. 5 perfume. But the boys’ chalet probably smells of that hair gel Martin Aston uses, so I’m glad I’m not staying there.
