Dia de Muertos + Sicarios + Family - S3-E5
Other mistake: A caption is misspelled towards the end - it says "cementario" when it should be "cementerio". (00:36:20)
Lidar + Rogues + Duty - S3-E16
Other mistake: MacGyver arrives at an airplane crash site. It is smoking. Yet this is supposedly days after the crash. And there is no evidence of fire anywhere. (00:11:25)
Soccer + Desi + Merchant + Titan - S4-E5
Other mistake: A spectator has a vuvuzela in his hand. This is a horn that emits a very loud monotone. It is common at soccer matches where he is. But what is he doing with it? He is looking through it as if it were a telescope. (00:32:05)
Diamond + Quake + Carbon + Comms + Tower - S5-E10
Other mistake: MacGyver makes a diamond in his kitchen to mount on a ring to propose to Desi. He shows it to Bozer, and - miracle of miracles - it is already faceted. (00:01:30)
