The Meiling and Sakuya interactions are like a Greatest Hits version of Kanna and Sumire. Also, I am curious as to how Remilia took the revelation that Gryphon is an immortal time and dimension traveler. Having Sakuya around probably helps woth that fundamental realignment of worldview, I imagine.

"And I assume the Laws of Time don't let you tell me when you first meet me?"

"You assume correctly."

"Right. Lu, remind me to repeal those when I get back to the office."
