Other mistake: When Bob is getting chewed out by his boss, his boss starts talking about clocks and says "there are also dual cogs." However, the subtitles say "there are also jewel cogs", and the subsequent conversation therefore makes little sense. (I saw this on the collector's edition DVD).
Continuity mistake: When Mr. Incredible is packing his suitcase just before he goes to Edna's to fix his old supersuit, the formal suit is blue, but later on just before he leaves and Helen tells him, "Have a great day honey" his formal suit turns black. (00:42:48)
Continuity mistake: When Mr. Incredible lands on the train tracks after trying to get the bomb off Syndrome that Bomb Voyage puts on him, underneath the tracks in the first shot there is no traffic but in the next shot when the train is coming, the shot zooms out and traffic just magically appears out of nowhere. (00:08:07)
Revealing mistake: When The Incredibles and Frozone are about to fire the robot's rocket claw, Helen turns off the rocket with the first button on the remote (round button). When she fires the rocket, she turns it back on with the last button on the remote.
Chosen answer: She says "Well, I think Dad has made excellent progress today, but I think it's time we wind down now". It's a joke, pretending to be winding down a counselling session, based on the fact that her father has been baring his soul a bit while imprisoned.
