It's too long to fully translate, and most of it isn't particularly interesting, but there's some spots that definitely are! So I'll do those and skip over the rest. It's a little rougher than the cutscenes, not super literal.
Sidurgu: You showed up at the right time. I have something here for you, that you should read...
Sidurgu: But I'm asking myself if you even have the time to spare to keep us company. There's trouble in the air lately; I can smell it. I'm guessing the Scions are keeping you pretty busy....
(you tell him about the First)
Sidurgu: And I was right. You're an exorbitant pighead who always has to help and can never give up.
Sidurgu: What do you mean, you didn't know that? I knew it the moment I saw you!
Sidurgu: Think about it. The big hero, savior of countless innocents, excuse me, an entire world! Of all things a dark knight, who's practically obsessed with helping others. If that's not excessive, what is?
Sidurgu: You go to this shard and proceed to put yourself into some heroic epic without ever thinking of quitting.
Sidurgu: Of course it's clear to me that you also paid your price. Man always pays a price...
Sidurgu: But because you kept fighting, without ever thinking of giving up, you also inspired others to contribute to saving their world. That's how it sounds for me at least.
Rielle: [Player] certainly also has someone who they've taken into their heart, who they're fighting for.
Rielle: When we met the Moogles and your master, didn't they say that it's this feeling of love that gives you strength? Something like that?
Rielle: When you're able to make it through a great and terrible war like that, there must have been a whole lot of love involved, right?
Answer: Looks like Rielle wants to know something about love.
Sidurgu: T-that's not what I wanted to talk about...but I can say one thing: this Thancred that you talked about is a bad role model!
Sidurgu: To travel across the land with such a young girl and put her in all kinds of danger, and then even to claim that she's like a daughter to him...he's only thinking about himself!
Sidurgu: What is it, kid? Why are you staring at me like that?
Rielle: I never saw you as a father, Sidurgu.
