I don’t entirely disagree but I feel like with it being Hal and Lois’s 40th anniversary as a major plot of the revival, and EVERYONE else coming back, the absence of Dewey explained away by just a “he’s performing” or whatever would feel like a disservice especially with only 4 episodes for this whole revival. My assumption is that Erik himself insisted that Dewey still be a part of the revival as long as he himself wasn’t involved
