"The biggest oversight of the episode was Kurt and Blaine; they are arguably the biggest story arc on the series right now, and they had one scene together, during which they didn’t speak to each other or EVEN MAKE EYE CONTACT. The writers have mishandled Kurt’s side of their breakup so severely that as it stands, Kurt may be madly in love with Blaine and trying to come to terms with it, or he may be completely disinterested while Blaine is daydreaming about their wedding. We just don’t know. They’re telling half of a story, and they’re not even doing that well. This goes for all of the core couples that were broken up this season, really, but it’s most obvious with Kurt and Blaine."
