"Karofsky learns that It Gets Better.
The self-hating, closeted bully trope is a trope because it’s true — and all too common. I kept thinking Glee was going to forget about Karofsky like it forgets about everything else, but by some miracle they managed to weave him into the most glorious, wretched, brilliant, perfect storyline in the history of the show. He was a bully. He was a gay bully. He was a gay bully who was in love with Kurt. He was a gay bully who began to accept himself. He was a gay boy, standing in front of another gay boy, asking for his love. He was a gay boy who got bullied. He was a gay boy who tried to kill himself in his very best suit. He was a gay boy who saw the future with another gay boy and a beautiful son. He was a gay boy who lived.”
