Our Doppelganger

"Five years ago, you never would've chosen your love over your career. But today, you did."
"Looks like I'm getting dumber."
"No, just more courageous."
"Look, we all have been searching for the five doppelgangers, right?"
"But eventually, over time, we all become our doppelgangers."
"You know, these completely different people who just happen to look like us."
"Five-Years-Ago-Robin? That girl, she was pretty great."
"But Doppelganger-Robin? She's amazing."
