It’s not altogether ideal for 9-1-1: Lone Star to get held until the midseason, considering fewer people generally start watching network shows at that point (minus those that premiere after the Super Bowl).
Don’t count out a crossover for the two series, though, as 9-1-1 and Lone Star are set to pair up with each other again when 9-1-1 comes back from its winter hiatus sometime in March 2022, so fans will hopefully see a team up between the 118 and 126 again.
And it’s not quite clear why Fox has so far avoided pairing the spinoff with its predecessor to kick off the fall season, beyond the fact that Fox’s fall schedule has been filled with more sports programming in recent years, as well as more Masked Singer-inspired content.
