Last week's winter finale of Glee tackled the subject of gay teen suicide when a closeted football player is outed then bullied and tries to kill himself.
The character of Dave Karofsky (played by Max Adler) is a former bully himself who channeled his own self-loathing by tormenting one of the school's most openly gay students, Kurt Hummel (Chris Colfer). It is Kurt who is there for Karofsky and when he visits his former bully in the hospital, helps him imagine his future.
