"I'm a sycophantic courtier with an elegant repost."
it's REPOSE not REPOST
You can clearly hear her say repost. Not repose.
And you are clearly deaf because she says repose, not repost. Do you even know the definition of the word repost? It doesn't fit with the rest of the sentance at all.
To be sycophantic means to attempt to win favor from influential people by flattery, a courtier is a synonym for aristocrat, so what does "reposting a letter or message" have to do with either of that?
Repose means to be absent of movement or animation, aka "when in repose her face recalls the tranquility of a work by da Vinci".
So repose fits. Repost doesn't even make any sense even if she were to say it.
