Continuity mistake: At the beginning of the episode, the oil spray pattern cleans itself from the firefighters' face shields in the span of a few cuts.
Audio problem: At the end of the episode, Buck comes home and crashes on his bed. He sees his girlfriend reporting on TV. Just before the shot cuts, the reporter mouths a word but nothing comes out. The shot changes to others watching the report, and she continues talking.
Continuity mistake: In the first segment it says the baby was born in 2011. Then later in the show the baby is not even one, but the year says it is 2015. So the child should have been at least 3-4. Not an infant still. (00:00:11 - 00:13:16)
Continuity mistake: At the end, Hen is in the rage room. She puts on a helmet, but in the next shot, she is smashing some glass without wearing the helmet. (00:41:26)
In a Flash - S6-E10
Continuity mistake: As the kids are burying their dad in the sand, the sand around his head changes depending on the angles. There are hand marks that disappear.
Audio problem: The foley added when Taylor is explaining to Buck about the van down the road, they cut out Lizzie and it jumps immediately into the next word.
Continuity mistake: Buck and Eddie are putting tape over holes in the wall. During the conversation, Buck repeats the same action twice with the tape, depending on the angle of the shot.
Other mistake: The woodchipper is shown cutting wood, but is squeaky clean when the golfer sticks his hand in it to get the ball out.
