Why does Eugene WANT to get into the LG afterlife?

[Kish]

Yes, this.

"I see nothing serious--oh wait, I see something serious." It's no more or less speculative to presume that without the Blood Oath, the next line would have been "so go on up" than it is to presume that it would have been "oh wait, I see five more serious things."

(That said, like Jasdoif if I understand them, I think most likely if Rich wants to establish that more than the Blood Oath has always stood between Eugene and Celestia, he's likely to use the "this is what my cutaway didn't show you" technique he's used a few times.)
