"Do you have confidence in this brew, Miss Serbus?"
"Yes, I believe so, sir."
"Because, if you manage to kill me from me drinking your work, then you'll spend life in Azkaban. Is it true that they still employ capital punishment in America?"
"Yes, professor, although now they've outlawed it for mentally insane persons, or those under the age of sixteen. It's about time they did something about those laws. They seem terribly archaic."
"Capital punishment on the whole is an archaic practice, Miss Serbus."
"No, I don't think so, sir. If the person killed a mass number of people at one time, or picked off several innocent individuals over the years, or attempted to kill a child, justice can only be served if they themselves pay the price they dealt to their victims. What if it was someone you loved, professor? Wouldn't you, then, want the ultimate punishment for the killer?"
"It's not something I need to think about, Miss Serbus, for I love no one."
"Well, I am sorry for that, sir."
