When Seven is in the holodeck preparing her quarters and Neelix is in there, she is visited by the hologram of Chakotay. She stated that "I suppose this would make you my inaugural guest...." This statement is wrong clearly because Neelix was in her quarters before Chakotay was.
In the holodeck simulation where they are cooking, Seven tells Chakotay that his technique is flawed and he should guide the food with his left hand, but when she goes to demonstrate, she in fact does the exact opposite, holding the food in one place with her left hand, while moving the knife laterally across the cutting surface.
