That's what I like the show to answer more than satisfactorily.

From the spoilers, they are throwing 'love' as a reason why he resigned/retired, but I hope it's a whole lot bigger than that. I know Carver is trying to expand on the lore, but the Rit Ziem was meh, Metatron (although a good villain) was so out of nowhere, Naomi's rank/title was left under the rugh. Abaddon, is so far, the only real interesting thing they added to the lore, and I really really hope Cain redeems Season 9 for me, the same way Abaddon did for Seaosn 8.
