At 3:40, the side shot of Helly shows her moving her eyes, with one visible. It moves much faster than normal and shows the film was sped up for this shot.
It is odd that Petey and Helly both mispronounce 'wizened' (in the break room) in the same way, especially given that they've never met each other.
It just means that neither of them had heard the word pronounced before.
