Throw in a small, almost useless non-consequential scene. Only several seconds long. It would be him just being one of the Townsfolk walking up in the morning, having to go to work again, and saying:
"Work? I was just there yesterday! Damn I hate sequels, they just kill me".
The scene to the non-movie savvy would just think he is another of the Townsfolk waking up expecting a typical day.
We would never see him again, but for those who recognize him, they could just assume he had died already, at some point in the town disaster.
Lots of scenes get filmed/ post filmed with movies, and a short cameo with him would just tie things up nicely, and add a new piece to movie trivia.
