Dent said some more funny stuff in this episode. Got to love a good bad guy that makes you laugh! :)
Dent did however make the mistake of letting Ethaniel have full access to his operating system. It allowed him to change Dent and make him more human. As soon as Ethaniel gives Dent freewill he starts making use of it although it takes a moment for him to realize that he is different than how he was a second ago. Dent gets peeved and is upset at what Ethaniel has done, 'corrupted' his programming. In reality Ethaniel was making corrections and making it to where Dent did not have to be treated like a dog all the time and do as Banning says but apparently Dent did not care. He is a bit ignorant in that way.
