Neelix:
[after learning that he has the metreon disease] There's one good thing that will come from all this. When I first met you, I didn't know that your species only lived eight or nine years. I fell in love with you, without... knowing how lonely it would be to live without you after you're gone. Now that... I'm going to die first, I don't have to worry about it.

Kes:
Before I met you, eight or nine years seemed like an eternity. It never occurred to me that anyone could live longer. Now that we're together, no matter how many years we have left, it doesn't seem like enough. But the important thing is to cherish whatever time we have together - whether it's a day or a decade.
