Ok, I've had a read through and a number of people stood out to me, but Hades' latest reason for the whole Hermes/Hades incident seemed rather shaky to to me:
But after further reading I discovered that it is possible that he did indeed believe that Hermes' role claim was changed by Del...
Hermes then roared up at Hades' vote on him, he was then backed by Apollo, and then later on the massive Hades/Hermes argument ensued.
It would appear that whole problem sourced from two misinterpretations in a row. Firstly Hades' belief that Del had changed Hermes' actual role claim, and then Hermes believing that Hades was attacking him for joking around...
So where does that leave us? It appears we have a very eager to argue Hermes, who may be fishing for scum, or is just hot headed. And a Hades who doesn't like people who actually role claim, and will bite if you really want an argument.
Ehh, all that work and I don't have any definite reason to vote for either of them, I'll keep digging around.
