Cisco: And if you don't take us, we'll die anyway. Our brains get wiped, and that's it. That's the end of the world.
Barry: No, losing both of my best friends, and it being my fault...that's the end of my world! You may think it's worth the risk, but I couldn't live with myself.

Iris: You can't save monsters.
Harry: Marlize isn't a monster. Besides, the clock is ticking. It's 10 hours before enlightenment. What do we have to lose?
Iris: She stabbed me with a katana. Our lives are what we have to lose.
