Mass Effect 32012

Reaper:
Shepard...

Commander Shepard - Female:
You know who I am?

Reaper:
Harbinger speaks of you. You resist, but you will fail. The cycle must continue.

Commander Shepard - Female:
What are you talking about? We stopped Sovereign and the Geth. We stopped Harbinger and the Collectors. We've earned a straight answer!

Reaper:
It is not a thing you can comprehend.

Commander Shepard - Female:
We might surprise you.

Reaper:
You represent chaos, we represent order. Every organic civilization must be harvested in order to bring order to the chaos. It is inevitable. Without our intervention, organics are doomed. We are your salvation.

Commander Shepard - Female:
You're killing everyone in the galaxy in order to save us?

Reaper:
The cycle must continue. There is no alternative.

Commander Shepard - Female:
Organics and synthetics don't have to destroy each other!

Reaper:
The Battle for Rannoch disproves your assertion. Finish your war - we will be waiting. [shuts down and dies]
