Behold, Eck! - S2-E3
Continuity mistake: When Dr. Stone's assistant helps him up from the floor, there's a lopsided, circular diagram drawn on the chalkboard behind them. One shot later, the diagram has changed into a perfectly round circle and has moved itself several inches higher on the board. (00:06:10)
Behold, Eck! - S2-E3
Plot hole: Eck gives Dr. Stone one of his eyes so the scientist can create a lens to improve the alien's vision. At the end, Stone hands Eck the lens, but not the eye. When Eck puts on the lens, his missing eye reappears out of nowhere. (00:48:30)
Behold, Eck! - S2-E3
Continuity mistake: Eck tears a leaf from Stone's notebook. But the close-up insert of the page and the following shot of it being torn out reveal two completely different sheets of paper. The first has only a brief list of four names and addresses. The second is covered with handwritten notes. They don't match, yet they're supposed to be the same page. (00:04:05)
