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.
Trivia: At various times throughout the show you may notice Chris Colfer has a large red scar on the left side of his neck running from about half way on the side to the back of his visible lower hairline. He had surgery when he was eight to remove an infected lymph gland. It is most noticeable when singing "I Wanna Hold Your Hand" in "Grilled Cheesus" (00:28:05-00:28:15)and numerous times "Candles" on "Original Songs" (00:28:10, 00:28:20, 00:28:55 & 00:29:05-Most Noticeable).
