There was a boy once, out of dath ilan, who alone in his classroom declared that he would take an extra fifteen seconds to take off his expensive shirt before he jumped into a pool to save a child, if there was otherwise no prospect of the child's parents' insurance paying for his expensive shirt.
Is Keltham still that boy? Or has he now - just like everybody around him was very clearly thinking, though not saying it out loud, because that would be impolite, and also, who even needs to say it when it's obvious what you're thinking - has Keltham now grown out of it, just like his parents almost certainly secretly hoped he would?
