Gold Fever - S2-E2
Plot hole: Roscoe and Enos are chasing the boys. They are well ahead of the Sheriff and go up into a semi with a conveniently made ramp to lose the cops. The dust was dissipated enough that Roscoe, coming up from the rear, could have seen the General in the trailer. Roscoe couldn't be that blind. Plus the trucker couldn't miss the movements of the truck settling down from the sudden adding of two tons.
Coming Home - S1-E13
Plot hole: Amuro flies the Core Fighter to the refugee camp. Taking a plane to get just across a hill is already kinda a headshaker, especially with White Base being short on resources, including fuel that is an issue in this very episode.Anyway, he lands it in the middle of the camp, and the people there tell him to please hide it. Later in the episode, we see that Amuro indeed hid it, in the middle of some woods, covering it perfectly in branches and other things. How in the world did he get the fighter there and on his own did all the camouflage work on the huge thing, is a prodigy of off-camera work.
Royal Jelly - S2-E1
Plot hole: It's all very well for Albert to humm "bzz-bzz" to indicate that he has been eating too much Royal Jelly and is no longer entirely human. But "bzz" is just the noise of bees flying, it's not a sound that they deliberately produce. It makes no sense to SAY "bzz." Suppose he was turning into a horse instead, then he might say "Whinny!", but he wouldn't say "Clip clop clip clop."
