In general, Waterhouse isn’t good at just winging it, but he’s tired and pissed off and horny, and this is a fucking war, and sometimes you have to. He mounts the podium, dives for a round of chalk, and starts hammering equations onto the blackboard like an ack-ack gun. He uses well-tempered tuning as a starting point, takes off from there into the deepest realms of advanced number theory, circles back all of a sudden to the Qwghlmian modal scale, just to keep them on their toes, and then goes screaming straight back into number theory again. In the process, he actually stumbles across some interesting material that he doesn’t think has been covered in the literature yet, and so he diverts from strict bullshitting for a few minutes to explore this thing and actually prove something that he thinks could probably be published in a mathematical journal, if he just gets around to typing it up properly. It reminds him that he’s not half bad at this stuff when he’s recently ejaculated, and that in turn just fuels his resolve to get this Mary-fucking thing worked out.
