Arrow Quotes

Thea: I'm going to miss you. Everyday I miss you.
Oliver: Goodbye Speedy.
Thea: Bye Ollie.

I'm tired of waiting for the day when people stop being afraid of the Glades and start coming here to raise their families. To find opportunities for growth and change. To uplift our brothers and sisters. To be better than we ever were before. If we keep waiting, we might run out of time. That's why, from here on out, we don't wait for our future in the Glades. We make our future now.
