At first, Puck seemed like a sworn enemy of the Glee club. He played football and bullied Kurt.

While he still goes back and forth from tough jock to gleeful singer, there's clearly a soft side to this character. He's proud of his Jewish heritage and crushed on Rachel briefly.

He also knocked up Quinn. That was a big mistake.

Glee Quotes

I'm gonna miss all of you. I love you guys.

Puck

Blaine: I needed you. I needed you around and you weren't there. And I was lonely. And I'm...I'm really sorry.
Kurt: You don't think that I've been lonely? You don't think that I've had temptations? But I didn't act on it because I knew what it meant. It meant something horrible and awful.
