The Psychologist: It's destroying everything.

The Biologist: It's not destroying... It's making something new.

The Biologist: Then I have to ask: why did my husband volunteer for a suicide mission?

The Psychologist: So you're asking me as a psychologist?

The Biologist: Yes.

The Psychologist: Then, as a psychologist, I think you're confusing suicide with self-destruction, and they're very different. Almost none of us commit suicide, whereas almost all of us self-destruct. Somehow. In some part of our lives. We drink, or take drugs, or destabilize the happy job... or happy marriage.

The Biologist: [Startles, uncertain whether this was targeted at her]

The Psychologist: But these aren't decisions. They're impulses. And in fact, as a biologist, you're better placed to explain them than me.

The Biologist: What do you mean?

The Psychologist: Isn't the self-destruction coded into us? Imprinted into each cell.

Josie Radek: [to Lena, about the Shimmer] Ventress wants to face it. You want to fight it. But I don't think I want either of those things.

[last lines]

The Biologist: You're not Kane, are you?

Kane: No. I don't think so.

[pause]

Kane: Are you Lena?

[first lines]

Scientist: What did you eat? You had rations for only two weeks. You were there for nearly four months.

The Biologist: I don't remember eating.

Scientist: How long do you think you were in there?

The Biologist: Days. Maybe weeks?

The Biologist: The mutations were subtle at 1st; more extreme as we got closer to the lighthouse. Corruptions of form. Duplicates of form.

Scientist: Duplicates?

The Biologist: [She looks at the tattoo on her arm & lifts her arm up] Echoes.

Scientist: Is it possible these were hallucinations?

The Biologist: I wondered that myself... but they were shared among all of us. It was dreamlike.

Scientist: Nightmarish?

The Biologist: Not always. Sometimes it was beautiful.

[the movie then cuts back in time to show beautiful translucent single-tailed wormfish swimming alongside double-tailed duplicates. Lena is in a canoe on a swamp located quite near to a corpse that bears the same tattoo as Lena]

The Biologist: Oww. Ow.

[She clutches her arm - there is no tattoo yet. However, a dark blue mark has appeared at the same place on her arm]

Cass Sheppard: You're hurt?

The Biologist: It's just a bruise. I must have gotten that from the gator.

Scientist: Did it communicate with you?

The Biologist: It reacted to me.

Scientist: You really have no idea what it was.

The Biologist: [as she examines multi-coloured flowers] These are very strange.

The Psychologist: Why?

The Biologist: Well, they're all so different. To look at them you wouldn't say that they are the same species... but they're growing from the same branch structure... so it *has* to be the same species. It's the same plant! It's like they're stuck in a continuous mutation.

The Psychologist: A pathology?

The Biologist: Well... you'd sure as hell call it a pathology if you saw this in a human.

[Last lines]

The Biologist: You're not Kane, are you?

Kane: I don't think so. Are you Lena?

Scientist: Can you describe its form?

The Biologist: No.

Scientist: Was it carbon based?

The Biologist: I don't know.

[the team kill an alligator & examine it's mouth]

The Biologist: Lena: Whoa. It's exactly the same as the flowers. Look at the teeth. Concentric rows. Something here is making giant waves in the gene pool.

[the paramedic, Anya, holds the alligator's mouth open. She has no tattoo on her arm]

Cass Sheppard: Sharks have teeth like that, don't they?

The Psychologist: Do you think it's a crossbreed?

The Biologist: You can't crossbreed between different species.

Anya Thorensen: Lena, this is getting heavy.

[Later in the movie, Anya has acquired the tattoo]

The Psychologist: It's not like us... is unlike us. I don't know what it wants or if it wants but it'll grow until it encompasses everything. Our bodies and our minds will be fragmented into their smallest parts until no one part remains... Annihilation.

Mutated Bear: Help me!... Help me!
