Climbing Castle Walls (TID AU Heronstairs oneshot)

Will visits his older sister, Ella everyday. She had been at the London Institution for about three months now but it seemed like longer. Most people didn't even know she was there and that was the way Will liked it. The last thing Ella needed was her history being splattered across the everlasting walls of social media.

However, on one occasion of Will's daily visit, he meets a boy who suddenly sets his dark world alight in a blaze of silver fire. Everyone who went to the London Institution had a story, and Will was determined to find out Jem's.
