Clark Kent : A Kryptonian girl showed up at my doorstep. Her name is Kara. Last time that happened, you were behind it.
Jor-El : I know nothing of her arrival.
Clark Kent : She says she was sent here by her father, Zor-El. You might remember him, since he's your brother. Care to tell me why you ignored that branch of the family tree?
Jor-El : Whatever Zor-El wanted with you, it was not for the greater good of Krypton. He could not be trusted, and neither can his daughter.
Clark Kent : You can't blame Kara for the actions of her father. She's not here to cause any harm.
Jor-El : That is an emotional, human reaction. Be careful of your feelings, Kal-El. They can betray you.
Clark Kent : My feelings are part of who I am, whether you like it or not. Now, what about my training?
Jor-El : Your training starts with Kara. Watch over her, Kal-El. She poses a greater threat than you believe.
