|This needs a stretch.|
The grave is the final resting place of Flash Flannigan.
What's New, Scooby-Doo?
insert details here.
- The grave seems to have been made simply because everybody thinks that because Flash vanished, he must be dead; the circumstances of his death, if it actually happened, weren't revealed. A vigil would've been more appropriate, but that wouldn't have helped the rest of the episode.
