LMD Coulson II and Sibyl in “Unfinished Business”

What's the difference between a Chronicom and a human?

Sibyl

Time. Humans have a limited amount of it and therefore fear death. They act irrationally to prevent themselves or others from experiencing death. Chronicoms cannot die. Time has no consequence. You should ask yourself which category you fall into.

So, that's the difference that makes your species more valuable.

Sibyl

Less fleeting. With a home planet intact, we will exist long after you're gone. Once you realize that, you'll give up. Or... you'll run out of...

...Time. Yeah, you said that. I would argue that you're wrong about three things, if you don't mind.

Sibyl

Please.

First... the difference is sacrifice. Yeah, time is limited... which means sacrifice comes at a real cost... not just data. Heart and pain and blood and sweat and tears... all the good human stuff. And we will never give up.

Sibyl

You said I was wrong about three things. What's the third?

Me. You see, I haven't feared death for a long time.

Sibyl

Is that so?

Yeah. The fact is, dying... it's kind of my super power.
