Guinan and Tasha Yar in “Unfinished Business”

Guinan

Can I get you something, Tasha?

Tasha Yar

Guinan, I have to know something. What happens to me in the other time line?

Guinan

I don't have alternate biographies of the crew. As I said to the captain, it's just a feeling.

Tasha Yar

But there's something more when you look at me, isn't there? I can see it in your eyes, Guinan. We've known each other too long.

Guinan

We weren't meant to know each other at all! At least...that's what I sense when I look at you. Tasha, you're not supposed to be here.

Tasha Yar

Where am I supposed to be?

Guinan

Dead.

Tasha Yar

Do you know how?

Guinan

No. But I do know it was an empty death. A death without purpose.
