Continuity mistake: During Season 2, Episode 9 (Special Education), just as Blaine is singing "Hey soul sister, I don't wanna miss." for the last time, he is several feet in front of the other Warblers. But during the next shot, as he is singing ".a single thing you do.", he's right in front of them. So he jumped back several feet between two shots.
Continuity mistake: During "Theatricality", when the boys are singing "Beth", just as Puck sings "Me and the boys are Playin'" for the first time, Finn is visible sitting behind Quinn. Yet Finn went to sit down and sing with Puck and is obviously sitting with the boys in the next wide shot.
Continuity mistake: In "Hell-O", as Santana and Brittney are talking about the "hottest guys in the school", Santana's glass is almost empty. Yet two shots later, when she takes a drink, her glass is full. Also, when she says "Would you mind waiting in the car?" her glass is full and you can obviously see a slice of lemon in it. Yet in the next shot, when she says "And leave your credit card", her glass is only about 1/3 full and the lemon slice is gone.
Continuity mistake: Kurt informs Blaine that he flew in an airplane for the first time. This however is incorrect, as Kurt flew to Albuquerque NM for the 2010 Cheerios Championships. In the season 1 episode Sectionals it is mentioned the Cheerios Nationals are in Albuquerque and in the season 1 episode Funk The Cheerios return from Albuquerque the same day. 1500 miles in less than a day means they flew.DVCorvis
Continuity mistake: During "Don't Stop Believing" at the line "He took the midnight train going anywhere," Rachel extends her hand with her palm facing the floor. In the next shot, it instantly changes to her palm facing the seats of the auditorium. (Timecode listed for the director's cut of the episode.) (00:44:00)
Continuity mistake: When Mercedes is singing "Bust Your Windows", the blue rags on Kurt's car behind her change position several times. Also, Kurt is at first looking up at the hole in his windshield, then has his head down on the hood, and then is looking up at the hole again, over a series of 3 or 4 shots.
Continuity mistake: At the end of the episode when Kurt and Blaine are sat in the Lima Bean, the position of Blaine's hand where it props up his face changes. Whenever we see Blaine from the front, his fingers are curved slightly, but when we see Kurt (and the back of Blaine's head), his fingers are held straight so they do not interfere with the shot.dyeitblue
Continuity mistake: In "The Power of Madonna", during the Cheerios stilts routine, as the people on stilts lift one leg one after the other, they are in a V shape, and there are both girls and boys on stilts. Yet in the very next shot, as the people on stilts swing the other Cheerios around, there are only 3 Cheerios, all guys, on stilts, and they are in a straight line.
