I still feel kind of bad for Stella. Even though the plot synopsis seems to suggest that Stella is going to be something of a villain, it still hurts to see her struggling needlessly.
The prince was cold, but he was frustratingly not clear about what he was displeased by, and what his expectations were. He could have answered her question about clearing up the misunderstanding rather than being vaguely condescending. At this point, even if Stella is hiding some malicious intent underneath a facade or something, all she's done is make some awkward social faux pas'. And awkward social faux pas' are something I can empathize with...
