'Glee' celebrates Cory Monteith, Finn Hudson in 'The Quarterback' episode

This episode ("Sweet Dreams"), of course, wasn't meant to be a valedictory to Finn, though in hindsight it uncannily feels that way. What made Finn so special? Look no further than these last scenes: his sweetness, and joy for life, his capacity for love and his gift for redemption. It's all right here.

As fans well know, Finn's soul was conflicted. His father, a former Marine, had died when he was a toddler, leaving the son in a solitary struggle to meet the standards of a ghost. But "Sweet Dreams" actually offers a hint of closure. Finn had decided to take college seriously and become a teacher, and as Rachel sang "Don't Stop Believin' " in the audition, she imagined her former fiance at her side. This would, in fact, be Monteith's last musical performance on the show.

And so, finally, what makes Thursday's episode especially melancholy is that you -- or at least I -- suspect Monteith was never really acting at all over his four seasons. As many personal tributes have attested, the good, gentle, soulful, sweet and -- yes -- struggling Finn was simply a reflection of the man who played him. Fans won't just be saying goodbye to a TV character. They'll be saying goodbye to someone they love.
