英語版FF9日誌101 : Before I knew it,

 リンドブルムの街についてビビとジタンが話しています。

Vivi:

Lindblum is really a busy place. I've never seen this many people before. I wonder where people go if they wanna be alone...

Zidane:

Lindblum has always been like this. People come here from all over the world. Some of them come here to become airship engineers, sculptors, actors...

Vivi:

Wow...

Zidane:

I don't even remember why I came here my first time. Before I knew it, I was living here with my Tantalus brothers.

Vivi:

Do they still live here?

Zidane:

Yeah. Our hideout is in the Theater District. I'm gonna go there right now. Do you wanna come along?

Vivi:

Um, that's okay. I'm gonna go look around town.

Before I knew it, I was living here with my Tantalus brothers.

before I knew itで「気が付くと」という意味です。直訳すると「気が付くより前に」という意味ですが、気が付くより前にそうなってたという事は、ようは気が付いたらそうなってたという事ですね。（ややこしい
