- He's part of the crowd scene after the blizzard ends so that Mr Warren can thank God that he gets to go home at night.
- He's seen blaming a late-season loss on the coach playing one player too much in service to John making another horrible pun.
- He's in the crowd scene at the end of the hockey season.
- Finally, he shows up at Mike's sleepover as an extra friend.
We don't, however, see him as part of the cast after Mike leaves elementary school. We have the Four Horsemen of Mike, Brian, Gordon and Lawrence present as a tight group but Darryl appears to have been forgotten as he does not seem to attend the same junior high that they do. This, I should think, is an oversight on Lynn's part that accidentally corresponds to reality. Simply put, elementary schools and junior high schools tend to have different catchment areas which means that Darryl is a block too far to attend the same school as the other four. By the time they all get to high school, Darryl is someone Mike and the other three have pretty much forgotten about. This also corresponds to reality. Every so often, Mike will get stopped in the street by a man who looks like Boris Johnson and be asked if he remembers him from grade school and the Delicate Genius will blank the Hell out.
