Ah, the Gunpowder Plot!
Thanks, I knew it was one of the episodes near the end.
Thanks, Lila!
Yes, I do think that it was intentional on the writers' part. Lucrezia herself even mentioned how similar Alfonso was to Juan, remember? She said that his drinking was reminding her of her other brother, the one who ended up dead.
Well, if Alf suspected anything, he didn't dwell much on it after his cousin took over. Was it his cousin? The one who tricked Lucrezia?
