Later on...

Karlheinz: Young Ollie has a very great talent. I don't think you are aware how great it is, but he is attempting to use that very talent against your will.
Martle: Well, he is a very willful boy.
Karlheinz: Indeed, he is, Mr. Martle.  A very wilful boy.  A rather naughty boy, if I may be so bold, sir.
Martle: It's his mother... She, er... interferes.
Karlheinz: Perhaps they need a good talking to, if you don't mind my saying so. Perhaps a bit more. My girls, sir, they tried to outpost me at first.  One of them actually stole a packet of matches and tried to burn my computer down.  But I corrected them, sir.  And when my wife tried to prevent me from doing my duty I corrected her.
