Prometheus and the upside-down zombie (28 Years Later spoilers)

The upside down zombie with Jimmy's name carved down his chest had a crow (or raven? Can never tell the difference) eating away at his liver.

In Greek mythology, Prometheus is chained to a rock for betraying Zeus and giving fire to humans and sentenced to having an eagle eat his liver for eternity. It immediately stood out to me as I've always been sort of obsessed with the imagery of someone chained up who can't die (undead) constantly having their liver eaten. I wonder if there's gonna be any ties between Jimmy and Zeus as a sort of mad god - he definitley seems to be the authority figure in his community with his cute little tiara lol.
