Missed opportunity:
“I’ve been sent to help you, so please don’t be afraid. I am your servant in all things; for you, my Lady, are the last magical descendant of Merlin-”
“That’s ridiculous.”
(fleeting disorientation)
“For you, my Lady, are the last magical descendant of Ravenclaw-”
“I don’t believe you.”
(fleeting disorientation)
“For you, my Lady, are the bearer of a most marvelous destiny-”
Edit: (Personally, I prefer ”—she felt a momentary sense of disorientation - ”; it seems a little more subtle, but I guess that’s not the effect he’s going for.)
Random, low-confidence but possibly amusing prediction: in MoR the final obstacle of the third-floor corridor is called the Mirror of Vec, because it’s inscribed Noiti lovde talopart xet nere hocru oyt ube cafru oyt on wohsi.
It’s much more thematic, at least.
