- Helen Justineau: [Melanie stares at a cat poster] Do you want a cat?
- Melanie: [as blood still drips from her face] I already had one.
- Melanie: We're alive?
- Dr. Caroline Caldwell: Yes. You're alive.
- Melanie: Then why should it be us who die for you?
- Sgt. Eddie Parks: [seeing Melanie cock a pistol and check the chamber] Where did you learn that?
- Melanie: I watched you.
- Sgt. Eddie Parks: Of course you did.
- Sgt. Eddie Parks: [referring to the feral hungry kids upon discovering a devoured Kieran Gallagher] Dirty little *fuckers*.
- Melanie: They just want to live. Everybody wants that.
- Dr. Caroline Caldwell: [reads aloud what she is writing] Exquisite mimicry of observed behaviours. Question mark.
- Helen Justineau: Hope is the good thing that makes you be able to stand all the bad things.
- Melanie: But there isn't anything bad here. Is there?
- Dr. Caroline Caldwell: In dissection it's very clear. The fungus is wrapped around your brain like, ivy around an oak tree.
- Melanie: But I can talk. I'm like you.
- Dr. Caroline Caldwell: You're not like anything that's ever existed before.
- Melanie: Babies can't eat people.
- Dr. Caroline Caldwell: These ones did. The mothers were probably all infected at once, in a single incident. Then the embryos they were carrying took the infection as well... through the placenta... They ate their way out.
- Dr. Caroline Caldwell: [referring to the zombies] They gather in groups as they did in the base. We're not sure why.
- Melanie: They must be lonely.
- Sgt. Eddie Parks: [sarcastically] Oh... I hadn't though of that one.
- Kieran Gallagher: [surrounded by the feral hungry kids] You touch me,
- [shows a grenade]
- Kieran Gallagher: I'll blow you all to shit.
