I know this is the false hope for Tommy in 9-1-1 main series but still positive hope his main role in new spin-off.Not to give you false hope, but Tim Minear has been known to make things up as he goes along. Lou says that when he returned for this season, he was told there was a chance that Buck and Tommy would break up and Oliver only learned that Buck/Tommy would break up between filming episodes 3 and 4. Also, Tim is very busy right now being the showrunner for 911 and at the same time working with Ryan Murphy to create a new 911 spin-off/pilot for ABC.
