Rios: I said I would never do it again and then I fucking did it again.
Seven: Same.
Rios: Never again do what?
Seven: So many things. But, in this instance, never again kill somebody just because it's what they deserve. Just because it feels wrong for them to still be alive. You?
Rios: Never again let another self-righteous, hard-assed, old starship captain into my heart. Never again have to stand there and watch him die.
Seven: Was there anything you could've done to prevent it?
Rios: No, I guess there wasn't
Seven: Then I win.
