At first, I thought tacking on a "whodunnit?" to the story of GH's little Jake dying diminished its power. But as it has played out, the search for who hit Jake was just the prelude to an ancillary plot that carries a different kind of punch. Luke was behind the wheel of the car that killed Jake, and he'd been drinking. For years, imbibing has been part of dissipated Luke's roguish charm, and he fought the idea that it could have contributed to his grandson's death, insisting liquor doesn't impair him. The horrifying realization that Jake might be alive if he'd just acted more responsibly will haunt Luke forever. And it will raise awareness of the dangers of drinking and driving in a way no public service ever could.
