Plot hole: When Clark uses his heat vision to heat the metal door handle to prevent Desiree from escaping, he only heats one handle. I know that things were happening fast, but it wouldn't have taken him that much more time to heat both handles, which he should have done since there is no way he could have known that she would have tried that particular handle.

Trivia: When Clark confronts the Flash in his hotel room, he reads off the fake IDs Jay Garrick, Barry Allen and Wally West. Those are the secret identities of the first three men to be called the Flash in the comics. Also, this Flash says his name is Bart, like Bart Allen, the teen hero formerly known as Impulse and currently being called "Kid Flash." (00:10:35)

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.
