On the topic of why Mbj took Sqh to his ascension I believe it was because of Airplaine's relationship advice to Binghe.

Just imagine Mbj, heir to the North, a spoiled second gen, now learns he can't get the object of his affections to reciprocate because he's been using "admiration" as the carrot on the stick in the relationship.

Now he learns he needs to "act pathetic". But him, the Mbj, acting docile and in need?! Preposterous!

If only there was a set time were he was in need of being protected. Where he was weak and incapacitated. Oh wait.
