Maybe he'd figured it was gold dust.
Anyway, what I've got is not a nitpick but more like trivia. When Maria starts about Quintano and that she never heard of him Enrique says his full name being Gene Quintano and that he was their skiing teacher.
In fact Gene Quintano is a movie director/screenwriter. You can check out his career on IMDB or allmovie. Not Hollywoods best blockbusters, I might add. He wrote the Allan Quatermain movies with Richard Chamberlain and Sharon Stone. Probably the poorest rip off of Indiana Jones. He also wrote Police Academy 3 and 4 and directed National Lampoons Loaded Weapon 1 (probably his best).
I think the poison that was used was applied to this knife, passed to the mutton when it was cut and then activated by the wine. - MacGyver.
Sometimes you just have to die a little inside to be reborn and rise again as a stronger and wiser version of you.
It's better to be a little sad than to be fake content.
