Howerton may be busy with his new NBC sitcom A.P. Bio, but his former co-star says there’s still hope that Dennis Reynolds will return. “We really never want to do the show without Dennis,” says Day. “There is a possibility that maybe we would have Dennis in part of a season, not a complete season. I think we would still do a great season. There is a possibility that we have Dennis for an entire season, which would be fantastic.”
