Lol - not to go off-topic immediately but... Kellhus' conversation with Proyas actually implies that Moenghus the Elder genuinely wanted to stop the Consult from achieving their goal and that Kellhus' accusations against his father were, in fact, an error. So I'm quite happy to lay to rest that Meta-Moenghus theory (though, I won't put down Moenghus-Ascended).
Otherwise, I wonder what Meppa's purpose serves to Kellhus...
EDIT: Oh, and I think that Meppa is the Consult Kid from TTT, just to put that out there again.
