Agents of S.H.I.E.L.D., Season 5

Faulnok:
Sinara, holding your own against the Destroyer of Worlds, felling my own best warrior. It seems I underestimated you and your desire to climb higher in the ranks, within which I now have an opening. My brother confines you to his dungeon, denying you the right to shine. On my side, you will shine more radiant than the stars we will conquer. A warrior such as yourself deserves a leader worthy of your talents. I will show you things Kasius could never... [Kasius bayonets him in the back.]

Kasius:
Sinara is not some object to be taken. The truth, brother? We both know father sent me on a suicide mission. Two of my generals were dead at my feet, yes, because Sinara killed them. They were preventing me from fleeing the battlefield. You see, Sinara said, and I agree, that the battlefield is not my place. I'm not built for it. With the bloodshed left to her, I can focus on greater things, and have. I wasted so much time on my knees, seeking your approval. No more.

Faulnak:
You play god over a dead rock. But you're just a coward who hides, then stabs his enemies in the back.

Kasius:
And in the front [bayonets Faulnak in the chest]. A life spent. A life earned. [to Sinara] Think how warmly father will greet us when we avenge my brother's death and bring him the Destroyer of Worlds. Everything we've ever wanted will soon come to bear.
