This is the cover of one of the comics.

This looks good, but Riverdale was so bad I'm feeling somewhat cautious as well. Still this trailer was great.

I think it's based on a Sabrina comic that's been going for a few years. I never picked it up, but from what I saw it looked similar in tone.

"Isn't it Wonderful/Suteki Da Ne" from Final Fantasy X. The version with lyrics is gorgeous as well, but the violins in the instrumental version of the song are just incredible.

Been meaning to watch this, kinda reminds me of Yona of the Dawn haha.

I *love* her reactions. They're so great.

I think the title refers both to Pride and Al's conversation, and Hohenheim's defense of Al: "Don't you ever mock my son."

Lauralei Lee just posted her reaction to the trailer.

The author of the manga revealed a few things about Madame Christmas. Apparently she's Roy's dad's sister, and both of Roy's parents died when he was young, so she took him in. She's been running her hostess bar/information gathering business for quite a while now, and the fact that he grew up around that sort of thing really does explain quite a bit about Roy.

In terms of geography, in the previous episode Ed and Al were both in Resembool, then Al continued forward by train to some slums on the outskirts of Central City. Ed did the same some hours later. Here's a map too, if it helps: https://vignette.wikia.nocookie.net/fma/images/f/...
So, it's a several hour train ride, but definitely doable within a day or half a day.

When we last saw Hohenheim, he was in Liore, but there was a few months timeskip after that (I'm not sure if you picked up on it, so I wanted to mention it) between "The Promised Day" and "Looming Shadows".

As for how Lan Fan found the group, she and the other Xingese characters have mentioned that they can sense Chi several times, so that would make the most sense (and Central City is where she last saw Greedling anyway, so she probably would have headed in that direction regardless).

I hope that clears some things up!
