Other mistake: Just as Malcolm finishes opening the hatch on the alien pod, a graphical mistake appears towards the left side of T'pol's arm. It appears as if a section of the craft had been added with an overlay, which abruptly disappears as the cutting tool stops firing. (00:01:30)
Suggested correction: It doesn't disappear. It just falls into shadow when the cutting beam is turned off.
Revealing mistake: When examining the burnt human in sick bay, the body moves his eyelids towards the end of the camera zoom in during the reveal that the human had a Vulcan ancestor. (00:14:30)
