The Flash Quotes

One mystery I cannot figure out is why some people come into our lives and why some people go. Others become a part of you. Some friendships feel like they'll last forever and others end far too soon. Not every friendship is meant to last forever. What does last forever is the pain when that person is gone.

Barry

Ralph: I know I’m not built for love. And that’s okay.
Caitlin: Ralph Dibney, you are kind intelligent and compassionate. and most of all you put the needs of others before yourself. So that means you are built for love, and you deserve someone who loves you back.
Ralph: Caitlin…i’m sorry, I just don’t feel that about you...
Caitlin: What? Gross!
