Merrill: There are a lot of things I can take, and some things I can't. But what I can't take is when my older brother, who's everything that I want to be, starts losing faith in things. I saw that look in your eyes last night. I don't ever want to see that look in your eyes again.
Merrill: Move children! Vámanos.
Graham Hess: There is no-one looking out for us. We are all alone.
Ray Reddy: Don't open my pantry, Father. I found one of them in there and I locked him in.
Caroline: Old Mrs. Kendleman twisted her ankle, as she puts it, diving for her life when a bunch of school kids rode down the sidewalk on skateboards. She went down to Thornton's store this morning and started spitting on the new skateboards. Spitting! By the time I got there, Mrs. Kendlemen had sprayed the whole damn place. And she must have had a cold or something. I'm telling you, I won't eat for a week. So, what happened to your crops?
Graham Hess: Morgan, after you were born, the doctor gave you to your mother. When she first looked at you, you just stared right back. You both just stared at each other for longest time, and you didn't even cry.
Merrill: Excluding the possibility that a female Scandinavian Olympian was running around outside our house last night, what else might be a possibility?
Officer Caroline: I'm not done asking questions. And I don't appreciate sarcasm.
Merrill: Move, children. Vamanos.
Graham Hess: We're going to board up every window in this house.
Merrill: How do you know boards will do anything?
Graham Hess: Because they seem to have trouble with pantry doors.
Merrill: Everything has a weakness.
Graham Hess: My vote counts as two.
Morgan: That's bullshit. You're cheating.
Graham Hess: Morgan, calm down.
Morgan: We don't know anything yet.
Merrill: Hey, you guys okay?
Morgan: Some guy had a sign saying it was the end of the world.
Merrill: Don't worry.
Morgan: You won't let anything happen to us, right?
Merrill: No way.
Morgan: I wish you were my dad.
Merrill: What did you say? Don't you ever say anything like that again. Ever.
Graham Hess: I don't want any of you spending time with Tracy Abernathy alone. Understand?
Answer: It could be that they are affected by the chlorine in the tap water (humans are affected by chlorine to, just look at Mustard Gas) to a greater extent then humans. The vet is only speculating about the landing sites. And while it is true that humans are mostly water, it is saline (i.e. salty like sweat) and has different chemical properties to pure H2O.
Soylent Purple
Well water does not contain chlorine.
