We have so many thoughts right now, it's a bit hard to process. Samuel Larsen (Joe Hart) is AMAZING in his Glee debut performance of Gym Class Heroes' "Stereo Hearts." from Tuesday's Season 3, Episode 13: “Heart.” And Sam (Chord Overstreet) rapping? Awesome. But why does Quinn seem closer to Sam in this video than Mercedes does? And why does Joe appear to be singing to cheer up Rachel? Is there trouble in paradise with Finn!? So many unanswered questions!
