While Corrine is presenting, she states that the VFT takes Nitrogen and other chemicals out of the insects skeleton. This is incorrect because insects do not have bones and therefore no skeleton. They have what is called an exoskeleton.

When Victor was in the surveillance room with all of the cameras behind him, especially the camera where you see Lucas and Marshall in the lab, the monitor screens show that the time is 11:23 a.m. Earlier when Victor picked up the generator from Vaughn he told Vaughn to come to dinner. When the alarm goes off after Lucas destroys the generator, Vaughn shows up to take the blame. Vaughn was supposed to show up for dinner, he was there way too early to even eat lunch. How did he know to come from Blake Holsey at the exact time?
In Stopwatch, when Vaughn closely examined the chi-ball that Josie had left, it had markings on it. But the floating one didn't, and the two balls came together. Why would one of the chi-balls in the box have markings, and the other one not? Shouldn't they both be the same?

Josie is wearing pink in the mirror, and Corrine said that she will not touch the color pink. In the first episode, Wormhole, when Josie moves to Blake Holsey, she is wearing a pink jacket.
Corrine claims she can't sing outside of the shower. This is incorrect because we have heard an excellent voice from her in the episode "Storm".
Lucas said that he found a whole box of the Pearadyne computer chips in his and Marshall's room, why did they all go into the basement to look at a box of the chips?
