The Bone Clocks question

Jason Taylor, Hugo's cousin, is mentioned very briefly on p. 118 of my paperback copy of The Bone Clocks. If you recall, Jason's mom is Hugo's mom's sister (Aunt Helena to Hugo). When Hugo is at his parents' home from Cambridge for the holiday break before he heads off to Switzerland for the New Year. "What a pity you'll miss Aunt Helena at New Year," Mum tells me. [...] says Dad, [...] "What's Jason studying again?" "Something psycho-linguisticky," says Mum, "at Lancaster." [...] "But now he's settled on being a speech therapist, says Mum. "A st-st-stuttering sp-sp-speech therapist," says Nigel. "Not grown up and not clever, Nigel. A stammer has the be the best possible qualification for a speech therapist. Don't you think?"

Alan Wall appears on p. 80 of my copy. He's part of the crew at Black Elk Farm. "Last, there's a kid called Alan Wall, who sleeps in a tiny caravan parked round the side of the farmhouse. I saw him hanging out wash to dry when I was having a look around. He can't be more than a year of two older than me, but his body's tough as cables and he's tanned like tea. Debby told me he's a gypsy, or a traveler, as you're s'posed to say these days, and that Mr. Harty hires someone from his family every year, but Debby didn't know if it's a tradition or debt or superstition, or what."

Alan Wall is mentioned a couple more times during Holly's time at Black Elk Farm, but that's it as far as I know.
