It was essentially the set-up for a sequel. They were discussing how Hein was a brilliant "doctor" and how they intend to keep a low profile while experimenting for the Anti-Hippocratic Society.

They began talking about Gretchen. The girl talked about how much of a genius she was and how her body had been plasticized.
Then they discuss where they are going to study after this. The boy is going to study somewhere that they do anesthesia experiments on people. The girl says she's going to her father's family practice where there isn't much regulation. Basically they were both like the others and were going to experiment on people too.

That was the girl who was with Paula and Gretchen when Hein and his buddies were making the dead body twitch on the table.
She and her classmate turn out to be junior members of the Anti Hypocratic lodge, and they are discussing how they will be able to get away with questionable experiments once they have their own practices.
