This is the firefighter scene.

Laurie had set the house ablaze and trapped Michael inside her secret cell type hiding area [idk Srry😭], and set the house on fire. Her, Karen, and Allyson got out the house before the house was set on fire, firefighters came and three brave ones were able to build up the courage to step up. Michael was on the front porch standing there with a type of pole [again idk😭], and he ended up impaling one firefighter with it, and beating the other two with the pole he had.
