9-1-1 7X10: All Fall Down

So Bobby ended up having a heart attack from smoke inhalation. And the police seem convinced that it's arson. Meaning, both Athena and I are on the hunt for Amir. Going through some unofficial channels (i.e. Maddie), she manages to find out where he lives and pulls a gun on him as soon as he gets home.

She's insistent that he set the fire. He's insistent that he didn't. However, once she tells him she's bringing him down to the station to sort it all out, the cartel show up. Turns out, they were the ones who torched the house. And, now they want Amir. He goes amicably while Athena calls the cops. But they are, like, 14 minutes out, so Athena handles shit herself.

They've got Amir handcuffed and tied to a chair. And are planning to pay him back for killing this guys son (which Amir had nothing to do with). But just as they are about to stab him, Athena causes a disturbance and they all go to look for the source. She grabs one of the guys and holds a gun to his head. Just before this, she's tossed gasoline around and lights a match. The place goes up instantly flushing everyone outside where the cops are waiting. Athena helps Amir out, and then gets the call that Bobby is awake.

Shortly after, the all head back to work only to find out that Bobby (in his retirement, that he didn't tell anyone about) has been replaced with Gerrard who everyone hates. Bobby fully expected to get his job as captain back, so he's as surprised as everyone else.

Meanwhile, Christopher is so upset with Eddie, that he decides to move to Texas with his grandparents. Maddie and Chim become an emergency placement for Mara so she can stay near Karen and Hen and out of the group home. And it seems like Buck is still dating Tommy, but we don't get to see much of him.
