Loki: Almighty Thanos, I, Loki, Prince of Asgard... Odinson... The rightful king of Jotunheim, God of Mischief... Do hereby pledge to you, my undying fidelity. (Loki tries to stab Thanos)

Thanos: "Undying"? You should choose your words more carefully.

Loki: You... will never be.... a god. (Thanos chokes him and eventually snaps his neck)

Thanos: No resurrections this time.
