It’s a big stretch, but what about renaming it to “Just A Kid”? It’s a lot easier to justify frailty if we assume the survivor is only the size of a child themselves, though I’m all too aware of the other benefits/drawbacks that should also entail (higher recoil with guns, no access to big two-handed weapons, difficulty reaching things on counters, more hiding places, it just goes on). But hey, it’s also a vague reference to a notoriously difficult game, so that’s a plus I suppose.
