The Governor's Pleasure - S3-E1
Plot hole: The governor refuses to open the door for the prisoners when they have Vera hostage, and you can hear her saying "no" "return to your units" over the radio, which Channing had to overrule. Later on in the show somehow Vera doesn't know the governor refused and has to find out from Channing. But Vera was there next to the radio the whole time. They use normal radios without earpieces so there is no way she didn't hear. (00:38:05)
Plot hole: Lucien, Trustan and Aurora are somehow compelled to believe they are Mikaelsons, when no-one knew how to compel until Elijah compelled Aurora by mistake when they fled. So when did this supposed compelling happen? Did Elijah go back and do it later on? The siblings all had knowledge of him compelling them, so I'm confused exactly when they all learned of their ability.
The Daughters of Jerusalem - S2-E6
Plot hole: Dinah Fortescue's fingerprints are supposed to be on a teacup but she's wearing gloves in the flashback. So how did they get there? (00:24:35 - 00:33:34)
Plot hole: "Red" is somehow serving a life term or what for the execution murders of some Russian spies, her husband and his cronies had headed up. But her hubby somehow escaped any such sentencing.
Plot hole: It's revealed that the gym owned by Ray and Terry is a front for Ray to launder his income. This is why he doesn't want or can't sell it. Any person auditing that gym would know it doesn't bring enough income if the floors are in disrepair and the equipments garbage as Terry tells Pie when he gives him money to fix it up after Mickey pays him. Ray runs a consulting firm, he could launder millions through consulting, he has an office with employees. Get vending machines, anything that's cash. (00:42:00 - 00:44:20)
