So are you gonna tell me that a room full of firefighters not hear the bay door open, or a Diesel truck turn on and drive off. Please even a dog would know something is wrong. Second of all I doubt the Severide didn't have his phone and didn't decide to call CPD at the first intersection after being "kidnapped". Third do you really need to steal a fire engine to bomb a place, and also have the correct declas for the department that operates in the city where you are going to bomb whatever (spoilers they never specify what they are bombing) what is this Money Heist? And then just use the guy who just poked a hole in your comrade to drive the vehicle you stole from him. And finally I don't know but you wouldn't abandon the city that you work at with the cities equipment just because your friend is driving a truck with a bomb, and just be accompanied by two detectives, not a bomb squad, swat or troopers just two CPD detectives. Honestly this episode shouldn't have aired. This is no show is no longer Chicago fire but just Chicago. Barely any calls and if there are it's only one quick one. Would give 0 star if IMDB allowed it.
