Ok ... not getting the "quote" or even the "paste" functions to work ... oh well.
Riverdaleswhiteflash ... I actually think that there are four lessons that are taught in your Harrowing.
(1) Valor:
Spirits can be just as dangerous to deal with as Demons, labels aren't as cut and dry and one would wish while in the Fade.
(2) Sloth:
Although Demons are dangerous, there are times that dealing with them are necessary or even desirable, just never be foolish enough to forget that THEY have home front advantage.
(3) Rage:
Straight up resistance via force, crude but a necessary fact of life in the Fade when everything can literally eat everything else.
(4) Mouse:
"Combat is a test of will, so will is also combat?" The true threats of the Fade are those you never see until it's too late, and although Rage would have devoured your essence I'm not sure that it would have actually been able to truly possess you even had it won.

On Jowan, although I totally agree that since leaving the Circle Jowan has increased in his strength of will, I'm not entirely sure that him being able to face down a Desire Demon that isn't primarily focused on him when he was prepared to do so is the same as passing an actual Harrowing since it's my understanding that the entire point of the Harrowing is that the Mage has to be able to pass it at their weakest, roused from their bed in the middle of the night and thrust into the Fade while still rubbing the sleep from their eyes. (And although I can't prove it I wouldn't be surprised if the Mage wasn't run through some "special drills" or given some extra chores the day before as well.)
Also, am I completely misremembering things or wasn't Jowan supposed to be paid for the poisoning with vague promises of being allowed to return to the Circle? -- Assuming that my memory isn't failing me then I don't think he'd be able to have resisted whatever demon was playing Mouse's role, but of course if I am mistaken on Jowan's payment then said theory is probably unfounded.
