Klaus : You're back.
Stefan, Salvatore : Did you doubt me?
Klaus : Not for a second. I knew you'd pass the test. You still care for your brother, for your old life.
Stefan, Salvatore : I don't care about anything anymore.
Klaus : You put on a good show, Stefan. I almost believe you. Let's hope, for your brother's sake, he does. You never stop caring about family, do you? But every time you feed, the blood makes it easier to let go.
