There are a lot of changes coming to Glee in its final season, but one of the better ones is that it's focusing on the original core characters: Rachel, Kurt, Mercedes, Puck, and the rest of the first McKinley crew. The show's season six teaser trailer [1] just debuted, and these new gallery pictures of the cast are hitting us with pangs of nostalgia for the first, brilliant season. Glee returns with a special two-hour episode on Friday, Jan. 9, but until then, take a look at the photos below, stay tuned for more peeks at the final season, and indulge the fan in your life with the best gifts for Gleeks [2].
