Continuity mistake: When Clark exits the phone booth wearing his blue shirt, only the neck button is unbuttoned in the wide shot. Immediately in the next close-up shot, two buttons are undone. Then in the next shot of Clark's front side, the shirt is back to only the neck button being undone. (00:02:27)
Turbulence - S8-E16
Other mistake: In the article about the plane crash, the last paragraph starts to repeat the same sentence. After is says Mercer took over the operation, it repeats that she started in collaboration with Lex.
Continuity mistake: When Kara and Clark get off the elevator, there's no-one around them as they're walking away. In the next shot of Kara and the elevator, 3 people have suddenly gathered to look at the broken elevator. The elevator was off camera for less than 2 seconds, not enough time for 3 different people to get into the position they're in when they weren't close by to begin with.
Continuity mistake: When Lois is at the dam, looking at the card she previously tore, the numbers and markings are written differently than before.
Continuity mistake: When Lionel is watching the video and drawing Kryptonian symbols, some of the symbols change in between shots. For example, when he draws "minion" one of the dots is touching the square. When he writes the word, everything is nice and neat and the dots aren't touching anything.
Other mistake: When Clark looks at Oliver's newspaper clipping, there's a story about an AIDS hospice being saved. But the 2nd paragraph on talks about the 2nd meteor shower to hit Smallville that has nothing to do with the hospice being saved.
Continuity mistake: After Lois pins the sketch of the Green Arrow, the pushpin changes position. In some shots, it's across the top of the paper and in others it's in between the top of the sketch and top of the paper.
Other mistake: When Clark is in the girl's room and a noise comes from the closet, Clark uses his X-Ray vision to see there's a person in there because he can see the skeleton and is surprised to see it's Lois when he opens the door. However, it's been shown before that Clark can use his X-Ray vision to see objects and people through solid objects. He should have been able to see that it was Lois rather than just a skeleton of an unknown person.
Other mistake: Throughout the series, they reuse the same footage for establishing shots of the Talon. For example, one of the shots has the Talon sign say "Silent Film Festival" with a guy holding and bouncing a basketball as they walk pass the Talon is in s02e05 and s03e11 and other episodes, including s03e10 where it's the same people but the guy is holding his jacket and further back.
Continuity mistake: When Lionel and Lex are talking, after they sit down, near the end of the conversation, Lionel asks who Lex's source is. Lex is looking straight ahead. In the next shot, we see Lex turn his head to face his father. In the next shot, Lex is looking straight ahead again.
Continuity mistake: When Ryan gets hit by Martha's car, his comic book goes flying out of his hand. When he falls to the ground, he's holding his comic book again.
Other mistake: When Jimmy wakes up in 1940, on his desk calendar it's Saturday the 3rd. The newspaper says it's May 3rd, 1940, but that was a Friday.
Other mistake: Jonathan Kent's headstone says he was born September 1, 1954. However, in "Relic", we learn Jor-El visited Smallville in 1961, where he met Jonathan's parents and his mom was pregnant with Jonathan. And we know it was him since Hiram (his dad) wanted to name their son Gene and Jessica corrects him and says his name is going to be Jonathan. Plus, if he was born in 1954, he would have been 25 when he won the high school state championship instead of a more realistic 18 if he was born in 1961.
Other mistake: The bowling scorecard for Chloe and Lana is wrong. It shows Chloe knocking down 1 pin (-|1) in the first frame but getting 3 points, then a spare in the 2nd frame but only getting 1 point. The math is wrong until the 7th frame where is ends up showing the correct score. Lana's score is correct, except on frame 9 it shows she knocked over 6 pins on her first ball and is on her 2nd ball, but when it cuts to her, all 10 pins are up. Plus an unfinished 9th frame shouldn't show a score.
Audio problem: At the beginning, you hear the horses braying and the dog barking, but you can tell none of the animals are making those sounds. The sounds were added in afterwards.
Answer: No, there is no such character in the comics. He's a "meteor-freak" like all the other baddies on the show. The sound has something to do with him vibrating his vocal cords very fast to create a high-pitched squeal.
