“I couldn't bear the thought of Alex looking at me like I was a freak. It was bad enough that the looked at me as Jack's sister.”

“It's Lila--come on, Jack. She might be a little impulsive but that doesn't make her a sociopath.'I swivelled my gaze to Jack, trying my best not to look like a sociopath.”

“What I'm trying to tell you, Lila,' he said, his voice husky in his throat, "is that I've always been there, looking out for you, even when you didn't know it - even when you couldn't see me."My stomach flipped. Alex took hold of my hands and squeezed. "Nothing's changed. I'll be right there, I promise. You might not be able to see me, but I'll be there.”

“I wandered over to the motorbike and read the work Triumph on the side. 'How long has he had it?' I asked Jack. 'No. Over my dead body.' Jack's expression was hard. […] '[…] I told Dad I'd keep you safe and the Alex you know is not the Alex who drives that bike. He's not known to respect the speed limit.' Now I definitely wanted to go on it.”

“Alex shot her a look that was colder than liquid nitrogen.”

“Something’s up,’ I say, handing the phone back.‘Not necessarily,’ Jack says. ‘You think this is the first time Lila’s been hot-headed? Seriously, dude, you do remember my sister, right? Short, blonde, impulsive as shock therapy? Stubborn as a mule who won’t take no for an answer?’Does Jack ever listen to himself?Does he appreciate the irony of this statement? I shake my head at him in wonder.‘Hey, I’m not short or blond,’ Jack protests as he catches the look on my face.”

“Jack stares at me blankly. ‘A what?’ he asks. I choke back the laugh. ‘A boy. You know? A Y-chromosome holder? You don’t seem to notice them as much as you do the X-carriers.’ ‘What are you talking about?’ Jack asks, ‘A boy? She’s just a kid.’ I hesitate, wondering how Jack is only just doing the maths on this one now. ‘She’s seventeen. She’s not a kid anymore.’ Jack looks like he’s about to go all Incredible Hulk and burst out of his clothes before rampaging through the bar. He jumps off the stool. ‘If any boy ever lays a finger on my sister, I’m going to kill him,’ he says. Again I stare at him in silence, thinking of all the girls Jack has laid fingers and much more of his anatomy on besides. Poor Lila. If she ever wants to have a shot at a normal life, as in one that doesn’t require a vow of celibacy, she needs to stay in London.”
