Many fans may have overlooked the fact that Tiffany was pregnant throughout most of season 3. By the time the show concluded its third season, they were already expecting Aimee-Leigh Jr., who makes her first brief appearance during the season finale’s climactic monster truck scene.
As the narrative unfolds in season 4, it’s clear that Aimee-Leigh Jr. appears to be several years old. This presents a timeline inconsistency since only a year and a half has lapsed between the end of season 3 and the beginning of season 4. It’s possible that a change in casting for a more manageable child actor contributed to this mismatch, thereby complicating the show’s timeline.
