Ronan: The Orb is in my possession, as I promised.

Thanos: Bring it to me.

Ronan: Yes, that was our agreement. Bring you the Orb, and you will destroy Xandar for me. However, now that I know it contains an Infinity Stone, I wonder what use I have for you.

Thanos: Boy, I would reconsider your current course.

Korath: Master! You cannot! Thanos is the most powerful being in the universe.

Ronan: Not anymore.
