Professor Boriarty loves to spend large amounts of time talking about things that, while they might be important in the grand scheme of wonderfulness, truly impact the here and now very little. His primary tactic is to talk in long winded spurts, pausing for undetermined periods of time while his opponents wait anxiously to Gargle the next big wall of information in hopes of formulating a rebuttal.
But you can't rebutt nonsense, can you? Bring your PJs, the Prof makes it a long night.
