Plot hole: When Kalgan is torturing Lea, he says that he wants her father's countermeasures in case of emergency. But when she is rescued and finds out MacPhearson is a traitor who is working for Kalgan, Captain Devers is worried because MacPhearson knows all of the ship's countermeasures. If MacPhearson knows the countermeasures, then Kalgon does too, so there is no reason to bring it up while he is torturing Lea.
Plot hole: We see Tess wearing Catherine's clothes when Catherine is gone, but Catherine is much slimmer than Tess. They wouldn't fit without being altered and she had no time to do so.
Suggested correction: Katherine is also taller than Tess. The same size could fit a taller, slimmer woman and a shorter, less slim woman.
Plot hole: At Tim's funeral, Olivia's attorney tells her that Tim had himself removed from Olivia's Last Will and Testament, proving he loved her and didn't want her money. However, an attorney could not legally change a client's Will without that person's knowledge and drafting a revised version.
Suggested correction: Not true. Anyone can have themselves removed as a beneficiary of a will. This is done by signing an Affidavit of Disclaimer of Inheritance at such time as someone becomes aware that they have been included in a will as a beneficiary. This is what Tim meant when he said he had removed himself from Olivia's will.
Plot hole: In the game against Fayetteville, Crash puts down two fingers indicating he wants Nuke to throw the curve. When the camera then shows Nuke shaking him off, you can see Fayetteville has a runner on 2nd. Even in the minors the catcher will mix up the signs so the runner on 2nd couldn't steal them and tip the pitch. He'd never just hold down two fingers.
Plot hole: Three gunshots were fired for Kurt and Ram's "double suicide" and almost two minutes pass between shots 2 and 3. Doubtful two police officers could think they shot each other.
Suggested correction: An officer could think that one boy shot the other twice, killing him with the second bullet, before that boy was successful in killing him. The remaining boy would then kill himself. "Shot each other" might be a sloppy description, but basically, Kurt and Ram are both dead. There is a letter - forged by Veronica - which "reveals" that they were a couple. No signs of anyone else being involved. The police consider it a "double suicide" because they believe the letter.
Interesting theory, but I respectfully disagree with your correction. Three gunshots to two dead bodies, each with one bullet wound, would arouse suspicion despite what a letter found at the scene says. If one of the boys killed himself, there would be some evidence to support that such as powder burns around the wound or powder residue on his hands. In fact, a forensic scientist would have performed a GSR test on the hands of the shooters to confirm they did in fact fire the weapons.
