"So, how do we do the science thing?"

"I know things about people being sick, so I'll sneak around and pick some rooms and ask you to tell me what you can smell about each one."

“Sure. Then we can snack.”

"While you guys are doing science, I can go around and see who'll make the best food," Eliza suggests. "And if there's anyone who looks fun to turn."

“Now you’re thinking like a vampire!”

"Yeah!" She taps her chin thoughtfully. "I don't think I'll just pick for food who'll taste best, though. Some people are in the hospital for reasons that mean taking them out of the gene pool will improve it and some aren't, you know? And if the human gene pool improves then we'll get better people to turn."

“Technically for the guys you could just...”

Zeke makes a snip gesture around his groin. “Still, food is food.”

"It seems like a bother to do that when we have to eat anyway," she points out. "I mean, old people are food too, but if we can only take people out of the gene pool who should be out, that'll be faster."

“I know, I know, joke’s a joke.”

"Oh okay I didn't realize you were joking." 

“Come on Justin, let’s do science.”

"Science!" 

He runs off in search of suitable patients, then comes back with a mental list of rooms, which he leads Zeke to for sniff tests. 

Zeke sniffs his first subject.

Cancer.

"Smells sour. There's drugs and stuff, but his insides sound... sloshy?"

"Yeah! He has cancer, that does that."

Zeke smirks. "Point to me."

"Cancer was easy mode," he scoffs, leading the other boy to the next subject. 

More sniff.

Osteoporosis. 

"Less bones. I mean, they have all their bones, they're just... thin."

"How can you smell that?"

He shrugs. "Less of the stuff bones are made of."

"How do you smell there being less of something?"

Zeke laughs. “Same way you can smell there aren’t roses here.”
