Quinn: Do you know what growing up is about? *pause* Losing things. Six months. We'll all be gone. Together.
Mercedes: We'll keep in touch?
Quinn: Yeah but well it won't be the same? When we see each other it'll be a special occasion. It'll be different. I don't wanna grow up yet. I'm not ready to lose you girls.
...
Quinn: Look. I know I went a lil crazy.
*Mercedes and Santana chuckles*
Quinn: But I'm here now. I'm seventeen and I have the rest of my life in front of me. I love Glee club, and I love.you.girls. And when we're 27, or, 87, I want to still be able to look back on this next couple of months, and talk about how they were the best times of our lives. I can't do that if we're all not together.
