know it's a bit of a stretch, but I feel like when he's talking about "show me... by what principles art thou driven", that might be related to the use of 2 hours. They're (supposed to be, at least) defining abilities of the job, right? When you use your 2 hour, you're showing AV the principle that drives you.
I've heard people express confusion at "I have been freed by the chains...", but if you have to use your 2 hour to be able to lock his and defeat him, you sort of are freeing him by using the chains that bind him.
Then again, maybe I'm reading into it too much.
