Probably unintentional (though knowing MCR, maybe not), but look at the videos for "Na Na Na" and "SING." "Na Na Na," which comes first, seems fun and light-hearted. "SING" is a continuation of the storyline of "Na Na Na," but is more serious and a downer. Now look at Jet Star, the character played by Ray Toro. He has an eyepatch in "SING," which he didn't have in "Na Na Na." "It's all fun and games till someone loses an eye," anyone?
