Agents of S.H.I.E.L.D., Season 6

Sarge:
Do you really think you can beat me?

Daisy:
Yes. This time, I'll actually kill you.

Sarge:
Go ahead. It'd be easier than doing it myself. Come on! What are you waiting for?! Do it! Kill me, Skye! If it works on me, it'll work on her. But you have to do it now, before I get any stronger.

Daisy:
Wait...

Sarge:
You can't wait. Don't you understand? It's all coming back to me. The memories, the pain. Her song ringing through every bone in my body.

Daisy:
What memories?

Sarge:
It's too late for that. I'll lose control. I could kill everyone here. End it!

Daisy:
I can't do it.

Sarge:
You've always been capable of more than you think. Now do it. Do it! Do it.

Daisy:
You were gonna sacrifice yourself. It's what Coulson would've done.
